Checklist for installing update 1706 for System Center Configuration Manager

Applies to: System Center Configuration Manager (Current Branch)

When you use the current branch of System Center Configuration Manager, you can install the in-console update for version 1706 to update your hierarchy from a previous version.

To get the update for version 1706, you must use a service connection point site system role at the top-level site of your hierarchy. This can be in online or offline mode. After your hierarchy downloads the update package from Microsoft, you can find it in the console under Administration > Overview > Cloud Services > Updates and Servicing.

  • When the update is listed as Available, the update is ready to install. Before installing version 1706, review the following information about installing update 1706 and the checklist for configurations to make before starting the update.

  • If the update displays as Downloading and does not change, review the hman.log and dmpdownloader.log for errors.

    • If the dmpdownloader.log indicates the dmpdownloader process is asleep and waiting for an interval before checking for updates, you can restart the SMS_Executive service on the site server to restart the download of the update's redistribution files.

    • Another common download issue occurs when proxy server settings prevent downloads from http://silverlight.dlservice.microsoft.com and http://download.microsoft.com.

For more information about installing updates, see In-console updates and servicing.

For information about the versions of the Current Branch, see Baseline and update versions in Updates for System Center Configuration Manager.

About installing update 1706

Sites:
You install update 1706 at the top-level site of your hierarchy. This means you initiate the installation from your central administration site if you have one, or from your stand-alone primary site. After the update is installed at the top-tier site, child sites have the following update behavior:

  • Child primary sites install the update automatically after the central administration site finishes the installation of the update. You can use service windows to control when a site installs the update. For more information, see Service windows for site servers.

  • You must manually update each secondary site from within the Configuration Manager console after the primary parent site finishes the update installation. Automatic update of secondary site servers is not supported.

Site system roles:
When a site server installs the update, the site system roles that are installed on the site server computer, and those that are installed on remote computers, automatically get updated. Before installing the update, make sure that each site system server meets the prerequisites for operation with the new update version.

Configuration Manager consoles:
The first time you use a Configuration Manager console after the update has finished, you will be prompted to update that console. To do so, you must run Configuration Manager setup on the computer that hosts the console, and then choose the option to update the console. We recommend that you do not delay installing the update to the console.

Important

When you install an update at the central administration site, be aware of the following limitations and delays that exist until all child primary sites also complete the update installation:

  • Client upgrades do not start. This includes automatic updates of clients and pre-production clients. Additionally, you cannot promote pre-production clients to production until the last site completes the update installation. After the last site completes the update installation, client upgrades will begin based on your configuration choices.
  • New features you enable with the update are not available. This is to prevent the replication of data related to that feature from being sent to a site that has not yet installed support for that feature. After all primary sites install the update, the feature will be available for use.
  • Replication links between the central administration site and child primary sites display as not upgraded. This displays in the update pack installation status as a status of Completed with warning for Monitoring replication initialization. In the Monitoring node of the console, this displays as Link is being configured.

Checklist

Ensure that all sites run a version of System Center Configuration Manager that supports update to 1706:
Each site server in the hierarchy must run the same version of System Center Configuration Manager before you can start the installation of update 1706. To update to 1706, you must use version 1606, 1610, or 1702.

Review the status of your Software Assurance or equivalent subscription rights:
You must have an active Software Assurance (SA) agreement to install update 1706. When you install this update, the Licensing tab presents the option to confirm your Software Assurance expiration date.

This is an optional value that you can specify as a convenient reminder of your license expiration date. This date is visible when you install future updates. You might have previously specified this value during setup or installation of an update, or by using the Licensing tab of the Hierarchy Settings, from within the Configuration Manager console.

For more information, see Licensing and branches for System Center Configuration Manager.

Review installed Microsoft .NET versions on site system servers: When a site installs this update, Configuration Manager automatically installs .NET Framework 4.5.2 on each computer that hosts one of the following site system roles when .NET Framework 4.5 or later is not already installed:

  • Enrollment proxy point
  • Enrollment point
  • Management point
  • Service connection point

This installation can put the site system server into a reboot pending state and report errors to the Configuration Manager component status viewer. Additionally, .NET applications on the server might experience random failures until the server is restarted.

For more information, see Site and site system prerequisites.

Review the version of the Windows Assessment and Deployment Kit (ADK) for Windows 10 The Windows 10 ADK should be version 1607 or later. If you must update the ADK, do so before you begin update of Configuration Manager. This ensures the default boot images are automatically updated to the latest version of Windows PE. (Custom boot images must be updated manually.)

If you update the site before you update the ADK, see the blog Configuration Manager and the Windows ADK for Windows 10, version 1607 for a script that can be used to regenerate the boot images.

Review the site and hierarchy status and verify that there are no unresolved issues: Before you update a site, resolve all operational issues for the site server, the site database server, and site system roles that are installed on remote computers. A site update can fail due to existing operational problems.

For more information, see Use alerts and the status system for System Center Configuration Manager.

Review file and data replication between sites:
Ensure that file and database replication between sites is operational and current. Delays or backlogs in either can prevent a smooth, successful update. For database replication, you can use the Replication Link Analyzer to help resolve issues prior to starting the update.

For more information, see About the Replication Link Analyzer in the Monitor hierarchy and replication infrastructure in System Center Configuration Manager topic.

Install all applicable critical updates for operating systems on computers that host the site, the site database server, and remote site system roles: Before you install an update for Configuration Manager, install any critical updates for each applicable site system. If an update that you install requires a restart, restart the applicable computers before you start the upgrade.

Disable database replicas for management points at primary sites:
Configuration Manager cannot successfully update a primary site that has a database replica for management points enabled. Disable database replication before you install an update for Configuration Manager.

For more information, see Database replicas for management points for System Center Configuration Manager.

Set SQL Server AlwaysOn availability groups to manual failover:
If you use an availability group, ensure that the availability group is set to manual failover before you start the update installation. After the site has updated, you can restore failover to be automatic. For more information see SQL Server AlwaysOn for a site database.

Reconfigure software update points that use NLBs:
Configuration Manager cannot update a site that uses a network load balancing (NLB) cluster to host software update points.

If you use NLB clusters for software update points, use Windows PowerShell to remove the NLB cluster. For more information, see Plan for software updates in System Center Configuration Manager.

Disable all site maintenance tasks at each site for the duration of the update installation on that site:
Before you install the update, disable any site maintenance task that might run during the time the update process is active. This includes but is not limited to the following:

  • Backup Site Server
  • Delete Aged Client Operations
  • Delete Aged Discovery Data

When a site database maintenance task runs during the update installation, the update installation can fail. Before you disable a task, record the schedule of the task so you can restore its configuration after the update has been installed.

For more information, see Maintenance tasks for System Center Configuration Manager and Reference for maintenance tasks for System Center Configuration Manager.

Create a backup of the site database at the central administration site and primary sites: Before you update a site, back up the site database to ensure that you have a successful backup to use for disaster recovery.

For more information, see Backup and recovery for System Center Configuration Manager.

Plan for client piloting:
When you install an update that updates the client, you can test that new client update in pre-production before it deploys and upgrades all your active clients.

To take advantage of this option, you must configure your site to support automatic upgrades for pre-production before beginning installation of the update.

For more information, see Upgrade clients in System Center Configuration Manager and How to test client upgrades in a pre-production collection in System Center Configuration Manager.

Plan to use service windows to control when site servers install updates:
Use service windows to define a period during which updates to a site server can be installed.

This can help you control when sites in your hierarchy install the update. For more information, see Service windows for site servers.

Run the setup prerequisite checker:
When the update is listed in the console as Available, you can independently run the prerequisite checker before installing the update. (When you install the update on the site, prerequisite checker runs again.)

To run a prerequisite check from the console, go to Administration > Overview > Cloud Services > Updates and Servicing. Next, right-click Configuration Manager 1706 update package, and then choose Run prerequisite check.

For more information about starting and then monitoring the prerequisite check, see Step 3: Run the prerequisite checker before installing an update in the topic Install in-console updates for System Center Configuration Manager.

Important

When the prerequisite checker runs independently or as part of an update installation, the process updates some product source files that are used for site maintenance tasks. Therefore, after running the prerequisite checker but before installing the update, if you need to perform a site maintenance task, run Setupwpf.exe (Configuration Manager Setup) from the CD.Latest folder on the site server.

Update sites:
You are now ready to start the update installation for your hierarchy. For more information about installing the update, see Install in-console updates.

We recommend that you plan to install the update outside of normal business hours for each site when the process of installing the update and its actions to reinstall site components and site system roles will have the least effect on your business operations.

For more information, see Updates for System Center Configuration Manager.

Post update Checklist

Review the following actions to take after the update installation is finished.

  1. Make sure that site-to-site replication is active. In the console, view Monitoring > Site Hierarchy, and Monitoring > Database Replication for indications of problems or confirmation that replication links are active.
  2. Make sure each site server and site system role has updated to version 1706. In the console, you can add the optional column Version to the display of some nodes including Sites and Distribution Points.

    When necessary, a site system role will reinstall automatically to update to the new version. Consider restarting remote site systems that do not update successfully.

  3. Reconfigure database replicas for management points at primary sites that you disabled before starting the update.
  4. Reconfigure database maintenance tasks that you disabled before starting the update.
  5. If you configured client piloting before installing the update, upgrade clients per the plan you created.

Known issues

After you update to version 1706, each time the SMS_Executive starts the following warning status message is created by the SMS_CERTIFICATE_MANAGER:

  • Microsoft SQL Server reported SQL message 515, severity 16: [23000][515][Microsoft][SQL Server Native Client 11.0][SQL Server]Cannot insert the value NULL into column 'RowVersion', table 'CM_GF1.dbo.AAD_SecretChange_Notify'; column does not allow nulls. INSERT fails.

This message can be ignored. It occurs when no cloud services were configured for use before updating to version 1706. This issue will be resolved in a future release.
