Mover 云迁移Mover Cloud Migration

简介Introduction

我们的目的是在各种无法很好地配合使用的 Web 技术之间充当中介。Our purpose is to act as an intermediary between various web technologies that don't play nice together. 我们将从一个位置获取你的文件,并将它们复制到另一个位置。We take your files from one place and copy them to another. 无需下载,也无需监视 — 我们的 Web 托管应用程序可以完成所有工作!No downloads and nothing to watch over—our web-hosted app does all the work!

开展任何企业迁移都是一项艰巨的任务。Undertaking any corporate migration is a daunting task. 将数据移动到云时,需要考虑许多事项。When moving your data to the cloud, there are many things to consider.

文件处理摘要File processing summary

转移文件时,我们会将临时副本从 Office 365 下载到临时服务器,然后上传到 Office 365。When we transfer a file, a temporary copy is downloaded from Office 365 to a temporary server and then uploaded to Office 365. 成功上传后,将从临时服务器中删除该文件。Upon successful upload, that file is deleted from the temporary server. 迁移完成后,将销毁该临时服务器。When your migration is complete, that temporary server is destroyed. 任何日志数据都将在 90 天后过期,并且我们永远不会保留。Any log data expires in 90 days and is never retained by us. 除复制文件和文件夹以及共享权限外,我们不会执行任何其他操作。We do not perform any actions beyond copying files and folders and sharing permissions. 我们从不执行删除操作。We never perform delete operations.

与利益干系人沟通Communicating with stakeholders

对于任何组织而言,迁移都是一项重要工作。A migration is a significant undertaking for any organization. 试图掌握整个数据范围并与员工进行沟通非常复杂。Trying to grasp the entire extent of all data and communicating with your employees is complicated. 对此,我们感同身受!We sympathize!

在迁移之前、迁移期间和迁移之后,与用户群进行清晰有效的沟通至关重要。Before, during, and after a migration, it is critical to communicate clearly and effectively with your user base. 我们为你的过渡团队提供及时的支持和文档材料,帮助你与每个利益干系人就这些更改进行沟通。We provide timely support and communication materials to your transition team to help you communicate these changes with each stakeholder.

管理层 — 管理层需要掌握有关迁移方式和原因的简洁信息,例如成本、优势和期望。Management — Management needs succinct info about the how’s and why’s of the migration, such as costs, benefits, and expectations. 你必须描绘成功迁移的清晰蓝图。You must paint a clear picture about what a successful migration should look like. 管理某个部门时,详细信息非常重要。Granular info is important when running a department.

例如,销售经理需要知道运营将受到哪些影响,例如:如果需要,员工还能在周末工作吗?For example, the Sales Manager needs to know how operations will be affected, such as Can employees still work over the weekend, if needed?

用户 — 他们是你的重要员工。Users — These are your bread-and-butter employees. 他们需要知道何时进行更改,以及向谁提出问题或疑问。They need to know when changes are taking place and who to go to with questions or issues.

要解决的关键问题:Key questions to address:

  • 我们为什么要迁移数据?Why are we migrating our data?
  • 这对我有什么影响?How does it impact me?
  • 有哪些优势?What are the benefits?
  • 此更改将造成多大的干扰?How disruptive is this change going to be?

第三方 - 如果组织外部的人员有权协作处理文档,相关过程可能会中断,并且需要重新共享数据。Third parties — If people outside your organization have access to collaborate on documents, this could potentially be interrupted and require resharing of data. 我们将在指南中介绍此事件的最佳做法。We describe best practices for this event in our guide.

IT 技术支持/支持人员 — 如果贵组织足够大,可以为其他员工配备专门的支持人员,那么他们必须了解迁移的各个步骤。IT Helpdesk/Support staff — If your organization is large enough to have specific support staff for other employees, they must understand each step of the migration.

规划Planning

规划是迁移中最困难的一部分。Planning is the most difficult part of a migration. 这也是获得正确结果的最关键阶段之一。It is also one of the most critical phases to get correct. 为了顺利轻松地进行迁移,你必须收集相关的组织信息,确定项目日程表,并减少可能出现的意外。To have a smooth and stress-free migration, you must gather relevant organizational info, determine project timelines, and mitigate any surprises that may appear.

收集信息Gathering info

在迁移前,请务必收集所需的全部信息,以便顺利运行迁移。Before migration, it is important to gather all the info you need to run the migration smoothly. 确保已确认以下清单中的信息。Make sure you have confirmed the info from the following checklist.

迁移信息清单Migration info checklist

  • 要迁移的用户数Number of users to migrate
  • 数据所有权Data ownership
  • 数据分布Data distribution
  • 要迁移的数据量Amount of data to move
  • 要迁移的文件数Number of files to move
  • 单个文件大小和/或平均文件大小Individual file sizes and/or file sizes on average
  • 你的迁移团队有哪些成员?Who is your migration team?
  • 负责与我们联系的指定联系人是谁?Who is your designated contact with us?
  • 我们指定谁与你联系?Who is our point of contact with you?

扫描Scanning

为帮助你进行规划,我们提供了扫描功能。To help with your planning, we offer a scanning feature. 我们的扫描可识别有多少用户拥有数据以及需要迁移多少数据。Our scan identifies how many users own data and how much there is to move.

此扫描实际上是一种模拟的迁移预演,它没有设置目标位置,这有助于在开始迁移数据之前识别任何有问题的文件/文件夹。This scan is effectively a simulated dry-run migration, with no set destination, which helps to identify any problematic files/folders before you begin migrating data.

备注

首次设置迁移后,即可在“迁移管理器”中使用该扫描。The scan is available in our Migration Manager after you have first set up a migration.

请通读本指南以更好地了解完整的迁移过程,或者直接跳至“设置迁移”。Read through this guide to better understand the full migration process, or skip ahead to Setting Up the Migration. 有关如何运行扫描的详细说明,请参阅“扫描”。For detailed instructions about how to run the scan, see Scanning. 另请参阅运行 Mover 迁移See also Running the Mover migration

要迁移的用户数Number of users to migrate

每个 用户 均由唯一的源和目标配对来定义。Each user is defined by a unique source and destination pairing.

例如:For example:

  • user01@example.com => user02@example.comuser01@example.com => user02@example.com
  • user01@example.com => user03@example.comuser01@example.com => user03@example.com

由于它们具有不同的目标位置,因此将它们视为两个单独的 用户许可证These would be considered two separate user licenses because they have different destinations.

Mover 自动缩放传输并发。Mover automatically scales your transfer concurrency up and down.

数据分布Data distribution

确定整个用户群中的数据分布是迁移中极为重要的组成部分,因为我们以高度并行的方式复制数据,并且我们的服务器以每个云存储提供商可以处理的速度转移数据。Determining the distribution of data across the user base is an extremely important component of a migration because we copy data in a highly parallel manner, and our servers transfer data as fast as each cloud storage provider can handle. Office 365 对数据下载和上传的速率具有限制。Office 365 has rate limits for how fast data can be downloaded and uploaded.

同时迁移的用户越多,迁移的吞吐量就越高。The more users simultaneously being transferred, the higher our throughput for your migration. 强烈建议拥有超大型数据集的用户将数据分到更小的帐户,以便加快转移速度。We highly recommend that users with very large data sets be broken into smaller accounts to facilitate faster transfers.

备注

为了最大限度地提高吞吐量,用户拥有的数据不应超过 5 TB。To maximize throughput, users should not own greater than 5TB of data. 如果你拥有的用户越多,并且他们拥有的数据量越少,那么迁移速度就越快。The more users you have, and the smaller the amounts of data they own, the faster your migration proceeds.

例如:For example:

  • 如果某个用户拥有 10 TB 的数据,我们建议将其分给 10 个用户,以便每个用户拥有 1 TB 的数据。If one user owns 10 TB of data, we recommend dividing that between 10 users so that each one owns 1 TB.

如果无法分解数据,则不应妨碍其他用户迁移。If data cannot be broken up, this should not hinder other users from migrating. 通常,拥有大量数据的用户需要大量时间来完成迁移。As a general rule, users with a lot of data require a lot of time to migrate.

要迁移的数据量Amount of data to move

了解要迁移的数据总量有助于为迁移创建更加实用的日程表。Knowing the total volume of data you are moving helps to create a more realistic timeline for your migration.

你的迁移团队Your migration team

建立迁移团队,让其领导贵组织完成相关项目。Establish a migration team to lead your organization through the project. 该团队的职责包括与我们联系、接受培训以及在迁移过程中向员工通知每项更改。The team’s role includes liaising with us, undergoing training, and notifying employees of each change during the migration process.

对于联系人,IT 经理或 IT 主管是不错的选择,因为他们非常了解贵组织的体系结构。An IT Manager or the Head of IT is a good choice for our point of contact because they understand the ins and outs of your organization's systems. 为了确保顺利、成功地进行迁移,我们将在每个环节与你展开密切协作。To ensure a smooth, successful migration, we work closely together and are with you every step of the way.

日程表Timelines

实用Be realistic

计划、执行和完成迁移所需的时间取决于许多因素。The amount of time required to plan, execute, and wrap up a migration depends on many factors. 组织要求、预算、安全审查以及管理层的支持只是其中的几个因素。Organizational requirements, budget, security reviews, and support from management are just a few.

我们通常认为,企业迁移至少需要 30 天的时间来计划和执行。We typically see corporate transfers take a minimum of 30 days to plan and execute. 确保为每个阶段分配充足的时间,我们将在本指南后面的部分中进行介绍。Ensure you allot yourself enough time for each stage, which we cover later on in this guide.

评估你的用户群Evaluate your user base

计划迁移哪些用户以及何时迁移至关重要。It is critical that you plan which users are migrating and when. 问自己以下问题:Ask yourself questions like these:

  • 是迁移整个组织,还是只迁移几个用户?Is the entire organization migrating, or just a few users?
  • 是一次性迁移所有人,还是按部门、办事处或地区进行分批迁移?如果是,为什么?Is everyone migrating at once, or are you splitting them into batches like department, office, or region? If so, why?

备注

以这种方式进行分批迁移会增加复杂性,并且可能会延长迁移时间。Batching migrations this way increases complication, and may extend your migration.

建议在较慢的组织阶段(如周末)进行迁移,以避免工作中断。We recommend migrating during a slower organizational period, such as the weekend, to avoid work interruptions.

使帐户保持活动状态Keep your accounts active

从 Office 365 迁移到 Office 365 时,需要确保所有用户都处于活动状态且易于访问。When migrating from Office 365 to Office 365, you need to ensure all your users are active and accessible. 准确地知道 Office 365 何时关闭或过期是安全地规划足够的迁移时间的关键。Knowing exactly when your Office 365 may shut down or expire is key to safely planning enough time to migrate.

考虑迁移速度因素Consider migration speed factors

我们提供了迁移数据的最快方法,但是迁移速度仍可能受到瓶颈的影响。We're the fastest way to migrate your data, but the speed of your migration may still be affected by bottlenecks. 速度瓶颈包括但不限于:Speed bottlenecks include, but aren't limited to, the following:

  • 要迁移的文件和文件夹的数量Number of files and folders being moved
    • 从客观上来说,这是 Internet 上的最大速度限制,因为它决定了所需的操作总数。This is objectively the biggest speed limit on the Internet, as it determines the total number of operations required. 大多数提供商都将流入速率限制为每个用户每秒一个文件。Most providers rate limit their ingress to one file per second per user. 这并非普遍适用,但这是预估时可以使用的基准保守指标。This isn't universally true, but it's a baseline conservative metric you can use when estimating.
    • 我们在所有客户中观察到的平均值是 2.4 MB 的平均文件大小。Our observable average across our customers is a 2.4 MB average file size.
    • 了解文件大小是预估转移速度的必要条件。Knowing file size is necessary to estimate transfer speed. 如果你无法确定确切的数值,大多数服务可提供说明单个或平均文件大小的报告。If you are not able to determine exact numbers, most services can provide reports that illustrate individual or average file size.
  • 要迁移的数据总量。Total amount of data being moved.
    • 数据总量会影响速度,但最终会被文件数量所掩盖。Total data can affect speed, but it is ultimately overshadowed by the number of files.
  • 与源或目标 连接器 的服务器连接。Server connections with the source or destination Connector.
  • 权限或共享方案的复杂性(如果适用)。Complexity of permissions or sharing schemes, if applicable.

除了要迁移的数据大小以外,你会惊奇地发现,影响因素如此之大。What may be surprising is how large of an impact factors other than the size of the data you are moving can have.

例如,每迁移一个文件通常会耗费半秒的时间。For example, it is common for there to be half a second of overhead per file being moved. 如果要迁移 200,000 个文件,仅这一项就会耗费 200,000 秒或超过两天的时间!If you are moving 200,000 files, this would be 200,000 seconds or more than two days' worth of overhead alone!

可以说,我们之所以无法及时为你提供准确的预估,是因为在任何给定时间点上都有太多因素在左右判断。Suffice to say, we cannot give you exact estimates on time because there are too many factors at play at any given point. 在你阅读本节内容时,我们已简单复制总大小为数 GB 的几个文件或几百个包含少量数据的文件。By the time you have read this section, we could have easily copied several files totaling many GB, or a few hundred files equaling a small amount of data.

我们可以就预估与你展开对话。We are available to have a conversation with you about estimates.

通知利益干系人有关迁移的信息Notify stakeholders about the migration

员工对其数据有不同的需求,了解这些需求至关重要。Your employees have different needs with respect to their data, and it is paramount to know what those are. 列出所有部门的需求清单,联系其经理,并确定其流程和应用中的关键问题。Take a shopping list of all departments, contact their managers, and identify key concerns in their processes and apps.

请记住,虽然云存储有时只是文件的容器,但人们也可能将其用于第三方应用或更高级的协作。Keep in mind that while cloud storage is sometimes just a container for files, people might also be using it with third-party apps or for more advanced collaboration.
