迁移评估扫描:启用 IRM 的列表Migration Assessment Scan: IRM Enabled Lists

了解如何在迁移期间缓解启用 IRM 的列表的相关问题。Learn how to mitigate issues with IRM enabled lists during migration.

概述Overview

信息权限管理 [IRM] 功能可用于对内容进行加密,确保用户访问该内容时不能转发或对其进行操作。文件以未加密的格式存储在 SharePoint 中。用户访问受 IRM 保护的列表中的文件时,文件将在传输前进行保护。文件仅可在 Microsoft Office 等 IRM 支持的客户端应用程序中打开。Information Rights Management [IRM] is a feature that enables you to encrypt content when a user accesses it to ensure it cannot be forwarded or manipulated. The files are stored in an unencrypted format in SharePoint. When a user accesses a file in an IRM protected list, the file is protected prior to transit. The file can only be opened in an IRM supported client application such as Microsoft Office.

IRM 迁移过程涉及两个主要组件:There are two main components to the IRM migration process:

  • 将目标环境配置为支持 Microsoft Active Directory Rights Management。Configure the target environment to support Microsoft Azure Active Directory Rights Management.

  • 对源和目标 SharePoint 库禁用 IRM。这是必需操作,因为迁移工具会采用与用户相同的方式访问文件。如果在源中启用了 IRM,则迁移工具将接收加密文件并将该文件上传到目标环境中。这会生成无法再成功打开的文件。Disable IRM on the source and target SharePoint libraries. This is required as the migration tooling will access the files in the same manner as a user. If IRM is enabled on the source, the migration tooling will receive an encrypted file and upload that encrypted file to the target environment. This results in a file that can no longer be opened successfully.

数据迁移Data Migration

不迁移与列表和库关联的 IRM 设置。需执行以下过程,才能使迁移工具适当处理受 IRM 保护的库。此过程可确保内容已传输且在迁移后可访问。IRM settings associated with lists and libraries are not migrated. The following process is required to enable the migration tooling to properly handle IRM protected libraries. This process ensures that the content is transferred and accessible post migration.

  1. 在源列表和目标列表中禁用 IRM。Disable IRM on the source and target list.

  2. 迁移工具将从源复制文件并将其放在目标中。Migration tooling will copy the files from the source and place them in the target.

  3. 对源和目标列表启用 IRM。Enable IRM on the source and target list.

重要

系统将跳过 SharePoint 中配置为"无访问"(已锁定)的任何网站。若要查看锁定网站集的列表,请参阅锁定网站扫描输出。Any site that is configured as "No Access" (locked), in SharePoint will be skipped. To see a list of locked site collections see the Locked Sites scan output.

准备迁移Preparing for Migration

  1. 需要为 SharePoint 配置 IRM。IRM will need to be configured for SharePoint.

  2. 在该网站集的迁移事件之前,需要对源禁用 IRM。IRM will need to be disabled on the source list prior to the migration event for that site collection.

迁移后Post Migration

  1. 对已迁移的内容列表启用 IRM。Enable IRM on the migrated content list.

  2. 执行以下步骤,确保受 IRM 保护的库中的文档得到保护。Perform the following steps to ensure documents in IRM protected libraries are protected.

  • 从受 IRM 保护的列表中下载文档。Download a document from an IRM protected list.

  • 在客户端计算机上打开文档。Open the document on the client machine.

  • 如果文档受到保护,则在功能区下方显示状态。If the document is protected, there will be a status displayed beneath the ribbon.

扫描结果报告Scan Result Reports

下表描述了 IRMEnabledLibrary-detail.csv 报告中的各列。此扫描报告包含已启用 IRM 的列表和库。如果对场禁用了 IRM,则不执行扫描,且输出文件中将指出这一点。The following table describes the columns in the IRMEnabledLibrary-detail.csv report. This scan report contains lists and libraries that have IRM enabled. If IRM is disabled on the farm, the scan will not execute and the output file will indicate this.
