在 Configuration Manager 中规划内容部署迁移策略Plan a content deployment migration strategy in Configuration Manager

适用范围: Configuration Manager (Current Branch)Applies to: Configuration Manager (current branch)

以主动方式将数据迁移到 Configuration Manager Current Branch 目标层次结构时,源和目标层次结构中的 Configuration Manager 客户端都能继续访问在源层次结构中部署的内容。While you actively migrate data to a Configuration Manager current branch destination hierarchy, Configuration Manager clients in both the source and destination hierarchies can maintain access to content that you deployed in the source hierarchy. 还可使用迁移升级或重新分配源层次结构中的分发点,以成为目标层次结构中的分发点。You can also use migration to upgrade or reassign distribution points from the source hierarchy to become distribution points in the destination hierarchy. 在共享和升级或重新分配分发点时,此策略使你不必为你迁移的客户端将内容重新部署到目标层次结构中的新服务器。When you share and upgrade or reassign distribution points, this strategy can help you avoid having to redeploy content to new servers in the destination hierarchy for the clients that you migrate.

尽管你可以在目标层次结构中重新创建和分发内容,但你也可以使用下列选项来管理此内容:Although you can recreate and distribute content in the destination hierarchy, you can also use the following options to manage this content:

  • 将源层次结构中的分发点与目标层次结构中的客户端共享。Share distribution points in the source hierarchy with clients in the destination hierarchy.

  • 将源层次结构中的独立 Configuration Manager 2007 分发点或 Configuration Manager 2007 辅助站点升级成为目标层次结构中的分发点。Upgrade standalone Configuration Manager 2007 distribution points or Configuration Manager 2007 secondary sites in the source hierarchy to become distribution points in the destination hierarchy.

  • 将分发点从 Configuration Manager 源层次结构重新分配到目标层次结构中的站点。Reassign distribution points from a Configuration Manager source hierarchy to a site in the destination hierarchy.

在源和目标层次结构之间共享分发点Share distribution points between source and destination hierarchies

在迁移过程中,你可以将源层次结构中的分发点与目标层次结构共享。During migration, you can share distribution points from a source hierarchy with the destination hierarchy. 你可以使用共享的分发点,在不必重新创建内容的情况下使从源层次结构中迁移的内容立即可供目标层次结构中的客户端使用,然后将其分发给目标层次结构中的新分发点。You can use shared distribution points to make content that you have migrated from a source hierarchy immediately available to clients in the destination hierarchy without having to recreate that content, and then distribute it to new distribution points in the destination hierarchy. 当目标层次结构中的客户端请求部署到你已共享的分发点的内容时,可将共享的分发点提供给客户端作为有效的内容位置。When clients in the destination hierarchy request content that is deployed to distribution points that you have shared, the shared distribution points can be offered to the clients as valid content locations.

除了成为目标层次结构中客户端的有效内容位置外,从源层次结构中进行的迁移仍在进行时,还可以将分发点升级或重新分配到目标层次结构。In addition to being a valid content location for clients in the destination hierarchy while migration from the source hierarchy remains active, it is possible to upgrade or reassign a distribution point to the destination hierarchy. 可以升级 Configuration Manager 2007 共享的分发点并重新分配 System Center 2012 Configuration Manager 共享分发点。You can upgrade Configuration Manager 2007 shared distribution points and reassign System Center 2012 Configuration Manager shared distribution points. 在升级或重新分配共享的分发点时,该分发点将被从源层次结构中删除并成为目标层次结构中的分发点。When you upgrade or reassign a shared distribution point, the distribution point is removed from the source hierarchy and becomes a distribution point in the destination hierarchy. 升级或重新分配共享的分发点后,你可以在从源层次结构迁移完成后继续使用目标层次结构中的分发点。After you upgrade or reassign a shared distribution point, you can continue to use the distribution point in the destination hierarchy after migration from the source hierarchy is finished. 有关如何升级共享分发点的详细信息,请参阅计划升级 Configuration Manager 2007 共享的分发点For more about how to upgrade a shared distribution point, see Plan to upgrade Configuration Manager 2007 shared distribution points. 有关如何重新分配共享分发点的详细信息,请参阅计划重新分配 Configuration Manager 分发点For more about how to reassign a shared distribution point, see Plan to reassign Configuration Manager distribution points.

你可以选择共享源层次结构的任何源站点中的分发点。You can choose to share distribution points from any source site in your source hierarchy. 为源站点共享分发点时,会在该主站点和每个其他主站点上的所有符合条件的分发点上共享子辅助站点。When you share distribution points for a source site, child secondary sites are shared at each qualifying distribution point at that primary site and at each of the primary sites. 要符合作为共享分发点的条件,托管分发点的站点系统服务器必须设置为具有完全限定的域名 (FQDN)。To qualify to be a shared distribution point, the site system server that hosts the distribution point must be set up with a fully qualified domain name (FQDN). 将忽略设置为具有 NetBIOS 名称的任何分发点。Any distribution points that are set up with a NetBIOS name are disregarded.

提示

Configuration Manager 2007 不需要为站点系统服务器设置 FQDN。Configuration Manager 2007 does not require you to set up an FQDN for site system servers.

使用下列信息来帮助你规划共享的分发点:Use the following information to help you plan for shared distribution points:

  • 你共享的分发点必须满足共享的分发点的先决条件。Distribution points that you share must meet the prerequisites for shared distribution points. 有关这些先决条件的详细信息,请参阅 迁移的先决条件中的迁移所需配置For more about these prerequisites, see Required configurations for migration in Prerequisites for migration.

  • 共享分发点操作是站点范围的设置,它共享源站点和任何直接子辅助站点上的所有符合条件的分发点。The share distribution point action is a site-wide setting that shares all qualifying distribution points at a source site and at any direct child secondary sites. 在启用分发点共享时,你无法选择单独的分发点进行共享。You cannot select individual distribution points to share when you enable distribution point sharing.

  • 目标层次结构中的客户端可接收包的内容位置信息,这些包分发到从源层次结构中共享的分发点上。Clients in the destination hierarchy can receive content location information for packages that are distributed to distribution points that are shared from the source hierarchy. 对于 Configuration Manager 2007 源层次结构中的分发点,这包括分支分发点、服务器共享上的分发点以及标准分发点。For distribution points from a Configuration Manager 2007 source hierarchy, this includes branch distribution points, distribution points on server shares, and standard distribution points.

    警告

    如果你更改源层次结构,原始源层次结构中的共享的分发点将不再可用,并且无法作为内容位置提供给目标层次结构中的客户端。If you change the source hierarchy, shared distribution points from the original source hierarchy are no longer available and cannot be offered as content locations to clients in the destination hierarchy. 如果重新配置迁移以使用原始源层次结构,则会还原以前共享的分发点作为有效的内容位置服务器。If you reconfigure migration to use the original source hierarchy, the previously shared distribution points are restored as valid content location servers.

  • 当你迁移共享的分发点上承载的包时,包版本在源层次结构和目标层次结构中必须相同。When you migrate a package that is hosted on a shared distribution point, the package version must remain the same in the source and destination hierarchies. 如果包版本在源层次结构和目标层次结构中不相同,则目标层次结构中的客户端无法从共享的分发点中检索该内容。When a package version is not the same in the source and destination hierarchy, clients in the destination hierarchy cannot retrieve that content from the shared distribution point. 因此,如果更新源层次结构中的包,你必须重新迁移包数据,然后目标层次结构中的客户端才能从共享的分发点中检索该内容。Therefore, if you update a package in the source hierarchy, you must re-migrate the package data before clients in the destination hierarchy can retrieve that content from a shared distribution point.

    备注

    查看共享分发点上托管的包的详细信息时,不会更新源站点“共享的分发点” 选项卡上显示为“托管的迁移包” 的包数量,直至下一个数据收集周期完成为止。When you view details for a package that is hosted on a shared distribution point, the number of packages that display as Hosted Migrated Packages on the source site's Shared Distribution Points tab is not updated until the next data gathering cycle is finished.

  • 可以从“管理” 作区的“源层次结构” 中查看共享的分发点及其属性,该工作区位于连接到目标层次结构的 Configuration Manager 控制台中。You can view shared distribution points and their properties in the Source Hierarchy node of the Administration workspace in the Configuration Manager console that connects to the destination hierarchy.

  • 无法使用 Configuration Manager 2007 源层次结构中的共享的分发点来承载 Microsoft Application Virtualization (App-V) 的包。You cannot use a shared distribution point from a Configuration Manager 2007 source hierarchy to host packages for Microsoft Application Virtualization (App-V). App-V 包必须迁移并进行转换才能供目标层次结构中的客户端使用。App-V packages must migrate and be converted for use by clients in the destination hierarchy. 但是,可以使用 System Center 2012 Configuration Manager 或 Configuration Manager Current Branch 源层次结构中的共享的分发点为目标层次结构中的客户端承载 App-V 包。However, you can use a shared distribution point from a System Center 2012 Configuration Manager or Configuration Manager current branch source hierarchy to host App-V packages for clients in a destination hierarchy.

  • 在共享 Configuration Manager 2007 源层次结构中的受保护分发点时,目标层次结构将创建一个边界组,其中包括该分发点的受保护网络位置。When you share a protected distribution point from a Configuration Manager 2007 source hierarchy, the destination hierarchy creates a boundary group that includes the protected network locations of that distribution point. 无法在目标层次结构中更改此边界组。You cannot change this boundary group in the destination hierarchy. 但是,如果为 Configuration Manager 2007 源层次结构中的分发点更改受保护边界信息,在下一个数据收集周期完成后,该更改将反映在目标层次结构中。However, if you change the protected boundary information for the distribution point in the Configuration Manager 2007 source hierarchy, that change is reflected in the destination hierarchy after the next data gathering cycle finishes.

    备注

    System Center 2012 Configuration Manager 和 Configuration Manager Current Branch 站点使用首选分发点(而不是受保护分发点)的概念。System Center 2012 Configuration Manager and Configuration Manager current branch sites use the concept of preferred distribution points instead of protected distribution points. 这种情况仅适用于从 Configuration Manager 2007 源站点中共享的分发点。This condition only applies to distribution points that are shared from Configuration Manager 2007 source sites.

从源站点中共享分发点前,Configuration Manager 控制台中不会显示合格的分发点。The eligible distribution points are not visible in the Configuration Manager console before you share distribution points from a source site. 共享分发点之后,只会列出成功共享的分发点。After you share distribution points, only the distribution points that are successfully shared are listed.

共享了分发点之后,你可以在源层次结构中更改任何共享的分发点的配置。After you have shared distribution points, you can change the configuration of any shared distribution point in the source hierarchy. 对分发点的配置所做的更改将在下一个数据收集周期后反映在目标层次结构中。Changes that you make to the configuration of a distribution point are reflected in the destination hierarchy after the next data gathering cycle. 你更新为符合共享条件的分发点会自动共享,而不再符合条件的那些分发点则会停止共享分发点。Distribution points that you updated to qualify for sharing are shared automatically, while those that no longer qualify stop sharing distribution points. 例如,你可能有一个分发点,该分发点未设置为具有 Intranet FQDN,并且最初未与目标层次结构共享。For example, you might have a distribution point that is not set up with an intranet FQDN and was not initially shared with the destination hierarchy. 为该分发点设置 FQDN 之后,下一个数据收集周期将识别此配置,随后与目标层次结构共享该分发点。After you set up the FQDN for that distribution point, the next data gathering cycle identifies this configuration, and the distribution point is then shared with the destination hierarchy.

计划升级 Configuration Manager 2007 共享的分发点Plan to upgrade Configuration Manager 2007 shared distribution points

在从 Configuration Manager 2007 源层次结构中迁移时,可以升级共享的分发点以使其成为 Configuration Manager Current Branch 分发点。When you migrate from a Configuration Manager 2007 source hierarchy, you can upgrade a shared distribution point to make it a Configuration Manager current branch distribution point. 可在主站点和辅助站点上升级分发点。You can upgrade distribution points at primary sites and secondary sites. 升级过程将从 Configuration Manager 2007 层次结构中删除分发点,并使其成为目标层次结构中的站点系统服务器。The upgrade process removes the distribution point from the Configuration Manager 2007 hierarchy and makes it a site system server in the destination hierarchy. 此过程还会将分发点上的现有内容复制到分发点计算机上的新位置。This process also copies the existing content that is on the distribution point to a new location on the distribution point computer. 然后,升级过程将修改内容的副本,创建单一实例存储以用于目标层次结构中的内容部署。The upgrade process then modifies the copy of the content to create the single instance store for use with content deployment in the destination hierarchy. 因此,在升级分发点时,不必重新分发 Configuration Manager 2007 分发点上承载的已迁移内容。Therefore, when you upgrade a distribution point, you do not have to redistribute migrated content that was hosted on the Configuration Manager 2007 distribution point.

Configuration Manager 将内容转换为单实例存储后,Configuration Manager 会删除分发点计算机上的原始源内容以释放磁盘空间。After Configuration Manager converts the content to the single instance store, Configuration Manager deletes the original source content on the distribution point computer to free up disk space. Configuration Manager 不会使用原始源内容位置。Configuration Manager does not use the original source content location.

并非所有可以共享的 Configuration Manager 2007 分发点都适合升级到 Configuration Manager Current Branch。Not all Configuration Manager 2007 distribution points that you can share are eligible for upgrade to Configuration Manager current branch. 为了具有升级资格,Configuration Manager 2007 分发点必须满足升级条件。To be eligible for upgrade, a Configuration Manager 2007 distribution point must meet the conditions for upgrade. 这些条件包括安装了分发点的站点系统服务器,以及安装的 Configuration Manager 2007 分发点的类型。These conditions include the site system server on which the distribution point is installed and the type of Configuration Manager 2007 distribution point that is installed. 例如,你无法升级安装在主站点的站点服务器计算机上的任何类型的分发点,但可以升级安装在辅助站点的站点服务器计算机上的标准分发点。For example, you cannot upgrade any type of distribution point that is installed on the site server computer at a primary site, but you can upgrade a standard distribution point that is installed on the site server computer at a secondary site.

备注

只能升级运行的操作系统版本对于目标层次结构中的分发点受支持的计算机上的那些 Configuration Manager 2007 共享的分发点。You can upgrade only those Configuration Manager 2007 shared distribution points that are on a computer that runs an operating system version that is supported for distribution points in the destination hierarchy. 例如,尽管可以共享运行 Windows Vista 的计算机上的 Configuration Manager 2007 分发点,但无法升级共享的此分发点,因为 Configuration Manager Current Branch 不支持将此操作系统用作分发点。For example, although you can share a Configuration Manager 2007 distribution point that is on a computer that runs Windows Vista, you cannot upgrade this shared distribution point because the operating system is not supported by Configuration Manager current branch for use as a distribution point.

下表列出了可升级的每种类型的 Configuration Manager 2007 分发点的受支持位置。The following table lists the supported locations for each type of Configuration Manager 2007 distribution point that you can upgrade.

分发点的类型Type of distribution point 位于站点系统计算机(而不是站点服务器)上的分发点Distribution point on a site system computer other than the site server 位于站点系统计算机(而不是站点服务器)上并承载其他站点系统角色的分发点Distribution point on a site system computer other than the site server and hosting other site system roles 位于辅助站点服务器上的分发点Distribution point on a secondary site server
标准分发点Standard distribution point Yes No Yes
位于服务器共享上的分发点1Distribution point on server shares1 Yes No No
分支分发点Branch distribution point Yes No No

1 Configuration Manager 对于站点系统不支持服务器共享,但支持升级位于服务器共享上的 Configuration Manager 2007 分发点。1 Configuration Manager current branch does not support server shares for site systems, but it does support the upgrade of a Configuration Manager 2007 distribution point that is on a server share. 在升级位于服务器共享上的 Configuration Manager 2007 分发点时,分发点类型会自动转换为服务器,并且必须选择将存储单一实例内容存储的分发点计算机上的驱动器。When you upgrade a Configuration Manager 2007 distribution point that is on a server share, the distribution point type is automatically converted to a server, and you must select the drive on the distribution point computer that will store the single instance content store.

警告

在升级分支分发点之前,请卸载 Configuration Manager 2007 客户端软件。Before you upgrade a branch distribution point, uninstall the Configuration Manager 2007 client software. 在升级安装了 Configuration Manager 2007 客户端软件的分支分发点时,将从计算机中删除以前部署到计算机的内容,并且分发点的升级将失败。When you upgrade a branch distribution point that has the Configuration Manager 2007 client software installed, the content that was previously deployed to the computer is removed from the computer, and the upgrade of the distribution point fails.

若要标识适合于 Configuration Manager 控制台(位于“源层次结构” 节点)中的升级的分发点,请选择源站点,然后选择“共享的分发点” 选项卡。适合的分发点在“适合升级” 列中显示“是” 。To identify distribution points that are eligible for upgrade in the Configuration Manager console in the Source Hierarchy node, select a source site, and then select the Shared Distribution Points tab. Eligible distribution points display Yes in the Eligible for Upgrade column.

在升级 Configuration Manager 2007 辅助站点服务器上安装的分发点时,将从源层次结构中卸载辅助站点。When you upgrade a distribution point that is installed on a Configuration Manager 2007 secondary site server, the secondary site is uninstalled from the source hierarchy. 尽管此方案称为辅助站点升级,但这种情况仅适用于分发点站点系统角色。Although this scenario is called a secondary site upgrade, this applies only to the distribution point site system role. 结果是不会升级辅助站点,而是会将其卸载。The result is that the secondary site is not upgraded and instead is uninstalled. 这会在曾经是辅助站点服务器的计算机上留下一个目标层次结构中的分发点。This leaves a distribution point from the destination hierarchy on the computer that was the secondary site server. 如果计划升级辅助站点上的分发点,请参阅本主题中的计划升级 Configuration Manager 2007 辅助站点If you plan to upgrade the distribution point on a secondary site, see Plan to upgrade Configuration Manager 2007 secondary sites in this topic.

分发点升级过程Distribution point upgrade process

可以使用 Configuration Manager 控制台来升级已与目标层次结构共享的 Configuration Manager 2007 分发点。You can use the Configuration Manager console to upgrade Configuration Manager 2007 distribution points that you have shared with the destination hierarchy. 升级共享分发点时,会从 Configuration Manager 2007 站点中卸载分发点。When you upgrade a shared distribution point, the distribution point is uninstalled from the Configuration Manager 2007 site. 然后其作为附加到目标层次结构中指定的主站点或辅助站点的分发点安装。It is then installed as a distribution point that is attached to a primary or secondary site that you specify in the destination hierarchy. 升级过程将创建在分发点存储的迁移内容副本,然后将此副本转换为单一实例的内容存储。The upgrade process creates a copy of the migrated content that is stored on the distribution point, and then converts this copy to the single instance content store. Configuration Manager 将某个包转换为单一实例内容存储时,会从分发点计算机上的 SMSPKG 共享删除该包,除非该包具有一个或多个设置为“从分发点运行程序” 的播发。When Configuration Manager converts a package to the single instance content store, it deletes that package from the SMSPKG share on the distribution point computer unless the package has one or more advertisements that are set to Run program from distribution point.

为升级分发点,Configuration Manager 会使用设置的“源站点访问帐户” 从源站点的 SMS 提供程序收集数据。To upgrade the distribution point, Configuration Manager uses the Source Site Access Account that is set up to gather data from the SMS Provider of the source site. 尽管此帐户仅要求具有站点对象的“读取” 权限即可从源站点收集数据,但是它必须还具有“站点” 类的“删除” 和“修改” 权限才能在升级过程中从 Configuration Manager 2007 站点成功删除分发点。Although this account requires only Read permission for site objects to gather data from the source site, it must also have Delete and Modify permission to the Site class to successfully remove the distribution point from the Configuration Manager 2007 site during the upgrade.

备注

Configuration Manager 一次仅可以将内容转化为一个分发点上的单一实例存储。Configuration Manager can convert content to the single instance store on only one distribution point at a time. 设置多个分发点升级时,分发点将排队等待升级并且一次处理一个分发点。When you set up multiple distribution point upgrades, the distribution points are queued for upgrade and processed one at a time.

在升级共享分发点之前,确保已迁移部署到分发点的所有内容。Before you upgrade a shared distribution point, ensure that all content that is deployed to the distribution point is migrated. 对于在升级分发点前未迁移的内容,在升级之后,它们将在目标层次结构中不可用。Content that you do not migrate before you upgrade the distribution point is not available in the destination hierarchy after the upgrade. 当你升级分发点时,迁移的包中的内容会转换为与目标层次结构的单一实例存储兼容的格式。When you upgrade a distribution point, the content in the migrated packages is converted into a format that is compatible with the single instance store of the destination hierarchy.

若要从 Configuration Manager 控制台中升级分发点,Configuration Manager 2007 站点系统服务器必须满足下列条件:To upgrade a distribution point from within the Configuration Manager console, the Configuration Manager 2007 site system server must meet the following conditions:

  • 分发点配置和位置必须适合升级。The distribution point configuration and location must be eligible for upgrade.

  • 分发点计算机必须具有足够的磁盘空间才能使内容从 Configuration Manager 2007 内容存储格式转换为单一实例存储格式。The distribution point computer must have sufficient disk space for the content to be converted from the Configuration Manager 2007 content storage format to the single instance store format. 此转换要求可用磁盘空间等于在分发点上存储的最大包的大小。This conversion requires available free disk space equal to the size of the largest package that is stored on the distribution point.

  • 作为目标层次结构中的分发点,分发点计算机所运行的操作系统版本必须受支持。The distribution point computer must run an operating system version that is supported as a distribution point in the destination hierarchy.

    备注

    当 Configuration Manager 检查分发点是否符合升级条件时,它不会验证分发点计算机的操作系统版本。When Configuration Manager checks for the eligibility of a distribution point for upgrade, it does not validate the operating system version of the distribution point computer.

若要升级分发点,请在“管理” 工作区中依次展开“迁移” 、“源层次结构” 节点,然后选择包含要升级的分发点的站点。To upgrade a distribution point, in the Administration workspace, expand Migration, expand the Source Hierarchy node, and then select the site that has the distribution point that you want to upgrade. 接下来,在“详细信息”窗格中“共享的分发点” 选项卡上,选择要升级的分发点。Next, in the details pane, on the Shared Distribution Points tab, select the distribution point that you want to upgrade.

通过查看“适合重新分配” 列中的状态,可以确认分发点已准备好进行升级。You can confirm that the distribution point is ready for upgrade by viewing the status in the Eligible for Reassignment column. 接下来,在 Configuration Manager 控制台功能区的“分发点” 选项卡上,选择“分发点” 组中的“重新分配” 。Next, on the Configuration Manager console ribbon, on the Distribution Points tab, in the Distribution Point group, select Reassign. 这将打开用于完成分发点升级的向导。This opens a wizard that you use to finish the upgrade of the distribution point.

在升级共享分发点时,必须将分发点分配给你在目标层次结构中选择的主站点或辅助站点。When you upgrade a shared distribution point, you must assign the distribution point to a primary or secondary site of your choice in the destination hierarchy. 升级分发点后,可与管理任何其他分发点一样,将分发点作为目标层次结构中的分发点进行管理。After the distribution point is upgraded, manage the distribution point as a distribution point in the destination hierarchy like any other distribution point.

通过选择“分发点迁移” 节点(位于“管理” 工作区的“迁移” 节点下),可以在 Configuration Manager 控制台中监视分发点升级的进度。You can monitor the progress of a distribution point upgrade in the Configuration Manager console by selecting the Distribution Point Migration node under the Migration node of the Administration workspace. 你还可以在目标层次结构的管理中心站点服务器上查看 Migmctrl.log 中的信息,或者也可以在负责管理已升级分发点的目标层次结构中的站点服务器上查看 distmgr.log 中的信息。You can also view information in the Migmctrl.log on the central administration site server of the destination hierarchy, or in the distmgr.log on the site server in the destination hierarchy that manages the upgraded distribution point.

备注

将分发点升级到目标层次结构时,将从 Configuration Manager 2007 源站点中删除分发点站点系统角色。When you upgrade a distribution point to the destination hierarchy, the distribution point site system role is removed from the Configuration Manager 2007 source site. 但是,已发送至分发点的包不会在 Configuration Manager 2007 层次结构中更新。However, packages that were sent to the distribution point are not updated in the Configuration Manager 2007 hierarchy. 在 Configuration Manager 2007 控制台中,已发送至分发点的包会继续将站点系统计算机列为“未知” “类型” 的分发点。In the Configuration Manager 2007 console, packages that had been sent to the distribution point continue to list the site system computer as a distribution point with a Type of Unknown. 如果对 Configuration Manager 2007 中的包进行后续更新,则将导致在站点尝试更新未知站点系统上的包时,该站点的 distmgr.log 中会出现分发管理器报表错误。Subsequent updates to the package in Configuration Manager 2007 result in Distribution Manager reporting errors in the distmgr.log for that site when the site attempts to update the package on the unknown site system.

如果决定不升级共享的分发点,则仍然可以在以前的 Configuration Manager 2007 分发点上安装一个目标层次结构中的分发点。If you decide not to upgrade a shared distribution point, you can still install a distribution point from the destination hierarchy on a former Configuration Manager 2007 distribution point. 必须首先从分发点计算机上卸载所有 Configuration Manager 2007 站点系统角色,然后才能安装新的分发点。Before you can install the new distribution point, you must first uninstall all Configuration Manager 2007 site system roles from the distribution point computer. 如果这是站点服务器计算机,则这包括 Configuration Manager 2007 站点。This includes the Configuration Manager 2007 site if it is the site server computer. 卸载 Configuration Manager 2007 分发点时,不会从计算机中删除部署到分发点的内容。When you uninstall a Configuration Manager 2007 distribution point, content that was deployed to the distribution point is not deleted from the computer.

计划升级 Configuration Manager 2007 辅助站点Plan to upgrade Configuration Manager 2007 secondary sites

使用迁移来升级 Configuration Manager 2007 辅助站点服务器上托管的共享分发点时,Configuration Manager 会将分发点站点系统角色升级到目标层次结构中的分发点。When you use migration to upgrade a shared distribution point that is hosted on a Configuration Manager 2007 secondary site server, Configuration Manager upgrades the distribution point site system role to be a distribution point in the destination hierarchy. 还会从源层次结构中卸载辅助站点。It also uninstalls the secondary site from the source hierarchy. 结果是 Configuration Manager Current Branch 分发点,而非辅助站点。The result is a Configuration Manager current branch distribution point, but no secondary site.

为使站点服务器计算机上的分发点适合升级,Configuration Manager 必须能够卸载辅助站点,以及该计算机上的每个站点系统角色。For a distribution point on the site server computer to be eligible for upgrade, Configuration Manager must be able to uninstall the secondary site and each of the site system roles on that computer. 通常,Configuration Manager 2007 服务器共享上的共享分发点适合升级。Typically, a shared distribution point on a Configuration Manager 2007 server share is eligible for upgrade. 但是,当辅助站点服务器上存在服务器共享时,辅助站点和该计算机上的任何共享分发点均不适合升级。However, when a server share exists on the secondary site server, the secondary site and any shared distribution points on that computer are not eligible for upgrade. 这是因为该流程尝试卸载辅助站点时,会将服务器共享视为附加站点系统对象,并且该流程无法卸载此对象。This is because the server share is treated as an additional site system object when the process attempts to uninstall the secondary site, and this process cannot uninstall this object. 在这种情况下,你可以在辅助站点服务器上启用标准分发点,然后将内容重新分发到该标准分发点。In this scenario, you can enable a standard distribution point on the secondary site server and then redistribute the content to that standard distribution point. 此流程不占用网络带宽,完成时,你可以卸载服务器共享上的分发点、删除服务器共享,然后升级分发点和辅助站点。This process does not use network bandwidth, and when finished, you can uninstall the distribution point on the server share, remove the server share, and then upgrade the distribution point and secondary site.

在升级共享分发点之前,审阅 Configuration Manager 2007 中的分发点配置以免升级仍要与 Configuration Manager 2007 一起使用的辅助站点上的分发点。Before you upgrade a shared distribution point, review the distribution point configuration in Configuration Manager 2007 to avoid upgrading a distribution point on a secondary site that you still want to use with Configuration Manager 2007. 这是不错的做法,因为升级辅助站点服务器上的共享分发点之后,将从 Configuration Manager 2007 层次结构中删除站点系统服务器,并且不再可与该层次结构一起使用。This is a good practice, because after you upgrade a shared distribution point that is on a secondary site server, the site system server is removed from the Configuration Manager 2007 hierarchy and is no longer available for use with that hierarchy. 如果删除了辅助站点,该辅助站点上的任何其余分发点将会孤立。When the secondary site is removed, any remaining distribution points at that secondary site are orphaned. 这意味着,它们将脱离 Configuration Manager 2007 的管理,并且不再共享或适合升级。This means they become unmanaged from Configuration Manager 2007 and are no longer shared or eligible for upgrade.

警告

在 Configuration Manager 控制台中查看共享分发点时,对于共享分发点位于远程站点系统服务器还是位于辅助站点服务器,没有可见的指示。When you view shared distribution points in the Configuration Manager console, there is no visible indication that a shared distribution point is on a remote site system server or on the secondary site server.

如果具有位于远程网络位置中的辅助站点,并且该辅助站点主要用于控制到该远程位置的内容部署,则考虑升级带共享分发点的辅助站点。When you have a secondary site in a remote network location that is used primarily to control the deployment of content to that remote location, consider upgrading secondary sites that have a shared distribution point. 由于可就何时将内容分配到 Configuration Manager Current Branch 分发点进行带宽控制设置,因此可以经常将辅助站点升级为分发点、为带宽控制设置分发点,并避免在目标层次结构的该网络位置上安装辅助站点。Because you can set up bandwidth control for when you distribute content to a Configuration Manager current branch distribution point, you can often upgrade a secondary site to a distribution point, set up the distribution point for bandwidth controls, and avoid installing a secondary site in that network location in the destination hierarchy.

用于升级辅助站点服务器上的共享分发点的流程与任何其他共享分发点升级的流程相同。The process to upgrade a shared distribution point on a secondary site server is the same as any other shared distribution point upgrade. 内容会复制并转换到目标层次结构正在使用的单一实例存储。Content is copied and converted to the single instance store in use by the destination hierarchy. 但是,升级辅助站点服务器上的共享分发点时,升级过程还会卸载管理点(如果存在),然后从服务器中卸载辅助站点。However, when you upgrade a shared distribution point that is on a secondary site server, the upgrade process also uninstalls the management point (if present) and then uninstalls the secondary site from the server. 结果,辅助站点会从 Configuration Manager 2007 层次结构中删除。The result is that the secondary site is removed from the Configuration Manager 2007 hierarchy. 若要卸载辅助站点,Configuration Manager 会使用设置的帐户从源站点收集数据。To uninstall the secondary site, Configuration Manager uses the account that is set up to gather data from the source site.

升级过程中,在卸载 Configuration Manager 2007 辅助站点后会出现一段延迟,然后才会开始在目标层次结构中安装分发点。During the upgrade, there is a delay between when the Configuration Manager 2007 secondary site is uninstalled and the when the installation of the distribution point in the destination hierarchy begins. 数据收集周期确定此延迟最高达四小时。The data-gathering cycle determines this delay of up to four hours. 延迟旨在为辅助站点提供新分发点安装开始前进行卸载的时间。The delay is intended to provide time for the secondary site to uninstall before the new distribution point installation begins.

当从 System Center 2012 Configuration Manager 的支持版本迁移到同一版本的层次结构时,可以将共享分发点从源层次结构重新分配到目标层次结构中的站点。When you migrate from a supported version of System Center 2012 Configuration Manager to a hierarchy of the same version, you can reassign a shared distribution point from the source hierarchy to a site in the destination hierarchy. 这类似于将 Configuration Manager 2007 分发点升级成为目标层次结构中的分发点的概念。This is like the concept of upgrading a Configuration Manager 2007 distribution point to become a distribution point in the destination hierarchy. 可从主站点和辅助站点中重新分配分发点。You can reassign distribution points from primary sites and secondary sites. 重新分配分发点的操作会从源层次结构中删除分发点,并使计算机及其分发点成为目标层次结构中所选站点的站点系统服务器。The action to reassign a distribution point removes the distribution point from the source hierarchy and makes the computer and its distribution point a site system server of the site that you select in the destination hierarchy.

在重新分配分发点时,你不必重新分发在源站点的分发点上承载的已迁移内容。When you reassign a distribution point, you do not have to redistribute migrated content that was hosted on the source site distribution point. 此外,与 Configuration Manager 2007 分发点的升级不同,分发点的重新分配不需要分发点计算机上的额外磁盘空间。Additionally, unlike the upgrade of a Configuration Manager 2007 distribution point, reassignment of a distribution point does not require additional disk space on the distribution point computer. 这是因为,从 System Center 2012 Configuration Manager 开始,分发点使用内容的单一实例存储格式。This is because beginning with System Center 2012 Configuration Manager, distribution points use the single instance store format for content. 在层次结构之间重新分配分发点时,不需要转换分发点计算机上的内容。The content on the distribution point computer does not need to be converted when the distribution point is reassigned between hierarchies.

要使 System Center 2012 Configuration Manager 分发点适合于重新分配,它必须满足下列条件:For a System Center 2012 Configuration Manager distribution point to be eligible for reassignment, it must meet the following criteria:

  • 必须在除站点服务器外的计算机上安装共享分发点。A shared distribution point must be installed on a computer other than the site server.

  • 共享分发点不能与任何附加站点系统角色共存。A shared distribution point cannot be co-located with any additional site system roles.

若要标识适合于 Configuration Manager 控制台(位于“源层次结构” 节点)中的重新分配的分发点,请选择源站点,然后选择“共享的分发点” 选项卡。适合的分发点在“适合重新分配” 列(在 System Center 2012 R2 Configuration Manager 之前的版本中,此列名为“适合升级” )中显示“是” 。To identify distribution points that are eligible for reassignment in the Configuration Manager console in the Source Hierarchy node, select a source site, and then select the Shared Distribution Points tab. Eligible distribution points display Yes in the Eligible for Reassignment column (this column is named Eligible for Upgrade prior to System Center 2012 R2 Configuration Manager).

分发点重新分配过程Distribution point reassignment process

可以使用 Configuration Manager 控制台重新分配从活动的源层次结构中共享的分发点。You can use the Configuration Manager console to reassign distribution points that you have shared from an active source hierarchy. 重新分配共享的分发点时,分发点会从其源站点中卸载,然后作为与你在目标层次结构中指定的主站点或辅助站点相连的分发点进行安装。When you reassign a shared distribution point, the distribution point is uninstalled from its source site and then installed as a distribution point that is attached to a primary or secondary site that you specify in the destination hierarchy.

为重新分配分发点,目标层次结构会使用设置的“源站点访问帐户”从源站点的 SMS 提供程序收集数据。To reassign the distribution point, the destination hierarchy uses the Source Site Access Account that is set up to gather data from the SMS Provider of the source site. 有关必需的权限和附加的先决条件的信息,请参阅迁移的先决条件For information about required permissions and additional prerequisites, see Prerequisites for migration.

同时迁移多个共享分发点Migrate multiple shared distribution points at the same time

从 1610 版起,可使用“重新分配分发点” 以便 Configuration Manager 可同时并行处理最多 50 个共享分发点的重新分配。Beginning with version 1610, you can use Reassign Distribution point to have Configuration Manager process in parallel the reassignment of up to 50 shared distribution points at the same time. 这包括支持的源站点中运行以下项的共享分发点:This includes shared distribution points from supported source sites that run:

  • Configuration Manager 2007Configuration Manager 2007
  • System Center 2012 Configuration ManagerSystem Center 2012 Configuration Manager
  • System Center 2012 R2 Configuration ManagerSystem Center 2012 R2 Configuration Manager
  • Configuration Manager (Current Branch)Configuration Manager (current branch)

重新分配分发点时,必须将每个分发点限定为已升级或已重新分配。When you reassign distribution points, each distribution point must qualify to be either upgraded or reassigned. 所涉及操作和过程的名称(升级或重新分配)取决于源站点运行的 Configuration Manager 版本。The name of the action and process involved (upgrade or reassign) depends on which version of Configuration Manager the source site runs. 这两种操作的最终结果是相同的:分发点及其内容就地分配给其中一个 Current Branch 站点。The end results for both actions are the same: the distribution point is assigned to one of your Current Branch sites with its content in place.

1610 版之前,Configuration Manager 一次只能处理一个分发点。Prior to version 1610, Configuration Manager could process only one distribution point at a time. 现在可以随意重新分配多个分发点,但会出现以下警告:Now you can reassign as many distribution points as you want with the following caveats:

  • 尽管不可选择要重新分配的多个分发点,但有多个分发点排队等候处理时,Configuration Manager 将采用并行处理,而不会等待当前处理完成后才开始下一个。Although you cannot multiselect distribution points to be reassigned, when you have queued up more than one, Configuration Manager will process them in parallel instead of waiting to finish one before starting the next.
  • 默认情况下,最多可同时并行处理 50 个分发点。By default, up to 50 distribution points are processed in parallel at a time. 第一个分发点的重新分配完成后,Configuration Manager 将开始处理第 51 个,依次类推。After the reassignment of the first distribution point is finished, Configuration Manager will begin to process the 51st, and so on.
  • 使用 Configuration Manager SDK 时,可以更改 SharedDPImportThreadLimit 以调整 Configuration Manager 可以并行处理重新分配的分发点数量。When you use the Configuration Manager SDK, you can change SharedDPImportThreadLimit to adjust the number of reassigned distribution points that Configuration Manager can process in parallel.

迁移内容时分配内容所有权Assign content ownership when migrating content

在为部署迁移内容时,你必须将内容对象分配给目标层次结构中的站点。When you migrate content for deployments, you must assign the content object to a site in the destination hierarchy. 此站点随后将成为目标层次结构中该内容的所有者。This site then becomes the owner for that content in the destination hierarchy. 尽管目标层次结构的顶层站点是迁移内容元数据的站点,但却是通过网络使用内容的原始源文件的已分配站点。Although the top-level site of your destination hierarchy is the site that migrates the metadata for content, it is the assigned site that uses the original source files for the content across the network.

为了最大程度地减少迁移内容时使用的网络带宽,请考虑将内容的所有权转让给目标层次结构中的站点,该站点在网络上与源层次结构中的内容位置接近。To minimize the network bandwidth that is used when you migrate content, consider transferring ownership of content to a site in the destination hierarchy that is close on the network to the content location in the source hierarchy. 由于有关目标层次结构中的内容的信息是全局共享的,因此该信息将在每个站点上可用。Because information about the content in the destination hierarchy is shared globally, it will be available at every site.

尽管有关内容的信息是通过使用数据库复制共享到所有站点的,但分配给主站点并随后部署到其他主站点上的分发点的任何内容将通过基于文件的复制传输。Although information about content is shared to all sites by using database replication, any content that you assign to a primary site and then deploy to distribution points at other primary sites transfers by file-based replication. 此传输将经过管理中心站点,并随后传送到其他主站点。This transfer is routed through the central administration site and then to the additional primary site. 分配站点作为内容所有者时,通过在迁移之前/过程中将你打算分发到多个主站点的包集中在一起,可减少低带宽网络上的数据传输。You can reduce data transfers across low-bandwidth networks by centralizing packages that you plan to distribute to multiple primary sites before or during migration when you assign a site as the content owner.
