移轉評估掃描:已啟用 IRM 的清單Migration Assessment Scan: IRM Enabled Lists

了解如何減輕啟用 IRM 的清單在移轉期間的問題。Learn how to mitigate issues with IRM enabled lists during migration.

概觀Overview

資訊版權管理 [IRM] 是一項能讓您在使用者存取時加密內容的功能,以確保內容無法轉寄或操作。這些檔案會以未加密的格式儲存在 SharePoint 中。當使用者存取受 IRM 保護之清單中的檔案時,該檔案會在傳輸前受到保護。檔案只能在 IRM 支援的用戶端應用程式中開啟 (例如 Microsoft Office)。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 移轉程序有兩個主要元件:There are two main components to the IRM migration process:

  • 設定目標環境以支援 Microsoft Azure Active Directory Rights Management。Configure the target environment to support Microsoft Azure Active Directory Rights Management.

  • 在來源與目標 SharePoint 文件庫上停用 IRM。這是必要程序,因為移轉工具存取檔案的方式會和使用者相同。如果來源環境上啟用了 IRM,移轉工具將會收到加密檔案,並將它上傳至目標環境,這會造成該檔案無法順利開啟。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.

資料移轉Data Migration

與清單和文件庫相關聯的 IRM 設定無法移轉。下列程序為啟用移轉工具以正確處理受 IRM 保護之文件庫的必要程序。此程序確保內容完成轉移,並能在移轉之後順利開啟。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. 停用來源和目標清單上的 IRM。Disable IRM on the source and target list.

  2. 移轉工具會從來源複製檔案並將它們置於目標環境。Migration tooling will copy the files from the source and place them in the target.

  3. 在來源與目標清單上啟用 IRM。Enable IRM on the source and target list.

重要

任何設定為「無法存取」(鎖定) 的網站在 SharePoint 中都將予以略過。若要查看鎖定的網站集合清單,請參閱「鎖定的網站」掃描輸出。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.

準備移轉Preparing for Migration

  1. 您需要為 SharePoint 設定 IRM。IRM will need to be configured for SharePoint.

  2. 您需要在該網站集合的移轉事件之前停用來源清單 IRM。IRM will need to be disabled on the source list prior to the migration event for that site collection.

移轉之後Post Migration

  1. 在移轉內容清單上啟用 IRM。Enable IRM on the migrated content list.

  2. 請執行下列步驟來確保 IRM 保護之文件庫中的文件受到保護。Perform the following steps to ensure documents in IRM protected libraries are protected.

  • 從 IRM 保護的清單中下載一份文件。Download a document from an IRM protected list.

  • 在用戶端電腦上開啟該文件。Open the document on the client machine.

  • 如果文件受到保護,其狀態會顯示在功能區下方。If the document is protected, there will be a status displayed beneath the ribbon.

掃描結果報表Scan Result Reports

下表描述的是 IRMEnabledLibrary-detail.csv 報表中各欄。此掃描報表包含啟用了 IRM 的清單和文件庫。如果陣列中的 IRM 已停用,將不會執行掃描,並於輸出結果中表示。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.
