Migrating Microsoft Teams

  1. Go to the main migration project Dashboard in case you use new migration UI. In case you are using classic experience or you are already on the Teams migration Dashboard, go to step 3.
  2. Click Teams widget.
  1. Open Teams and select the teams with provisioned state you want to migrate. Migration will be skipped for all teams that are not yet provisioned

TIP: It is recommended to select no more than 100 teams for the task to streamline the process. You can create several tasks that will be executed concurrently. Use search and filtering to quickly navigate through the list of teams.

  1. Select whether to migrate messages with attachments. The following options are available:
    • Migrate messages and files - could take a long time to complete.
    • Migrate messages only - recommended for fast synchronization of teams.
    • Use previously migrated files - use when On Demand Migration has already migrated files to the target. Teams messages migrated in this task will have access to files on the target.
    • Migrate group mailbox only - use to correct group mailbox issues.

When migrating Teams using Migrate messages only, message links will not work for files not yet migrated to the target. Re-migrate Teams using Migrate messages and files to correct this issue. To learn more, see Re-migrating messages and files.

TIP: Migration task may hang due to group mailbox migration issue. If this is the case, stop migration task and re-run the team migration with the Migrate messages and files option selected. Then repeat migration of these teams with Migrate Group Mailbox only option selected.

  1. Select whether to migrate OneNote including all related content. This option is selected by default.
  2. Select whether to migrate Planner including all related content. This option is selected by default.
  3. Select whether to migrate Word, Excel, and PowerPoint tab apps in the team channels. This option is selected by default.
  4. Select whether to migrate the Group Mailbox. This option is selected by default.
  1. Schedule when the task will be started. See Task Scheduling for details.
  1. Click Next to view the task summary. Name the task and check selected options. Click Finish to save or start the task depending on schedule option selected.

The migration task is created. You can track its progress in the Tasks, view the summary on the Dashboard or monitor alerts and notifications in the Events.

Important: The task status in task list only indicates the progress of this task. Completed status only means this task processing is completed. If the migration has any errors, the flag Migration partially failed will appear in the Teams/Group grid.

Renamed Channel Migration

When a channel is renamed, Microsoft does not rename the corresponding SharePoint Document folder for this channel, this is a known issue. For example, when Channel Channel 1” is renamed to “Channel_Renamed”, the folder name under the “Files” tab is still “Channel_1”. After migration is completed, all messages and files can be opened correctly. Consider, that these files cannot be displayed on the target Files tab. This is because all the files are still stored and migrated under ““Channel_1” folder. “Channel_Renamed” folder does not exist until you click the “Channel_Renamed” channel’s Files tab, then the system will generate an empty folder for it. But no files will be stored there. To avoid files and message association breaking it is not recommended to rename folders manually. If necessary, you can copy necessary files to “Channel_Renamed' folder, but these files won't associated with messages.

Re-migrating messages and files

To re-migrate messages and files, re-run the task following the steps outlined in Migrating Microsoft Teams. Select whether to migrate messages with attachments from the various options.

 

NOTE:

  • Delta query is used automatically.
  • The initial synchronization must have completed successfully in order for the delta synchronization to start working for further migrations.
  • Previously migrated messages will not be re-migrated via this process. We highly recommend you do not delete teams in the target tenant after migration.
  • See What We Migrate to consider what changes are supported to be updated.
  • It is recommended to perform re-migration before the source and target tenants will be switched.

 

Message updates

When Teams messages are re-migrated a delta query retrieves those messages that have been added or changed in the channels since the last synchronization. Messages that did not migrate completely previously, for example the attachment was unavailable, will be additionally migrated into new and modified messages.

File updates

Follow the steps outlined in Migrating Microsoft Teams and select Migrate messages and files.

NOTE: The file on the target if it already exists will be overwritten. All changes to the file on the target will be lost.

 

Migrating Microsoft Teams Chats

On Demand Migration for Teams helps you discover and migrate Microsoft Teams Chats for one or more matched users from a source tenant to a target tenant.

In this topic:

 

Considerations

  • It is a best practice to migrate Chats after all the content like OneDrive, Mail, SharePoint, Teams, etc., is migrated and the user accounts are matched.
  • You must use dedicated Azure AD administrator accounts for migrating Chats. For more information, see Prerequisites and Azure AD administrator accounts.
  • During migration, the migration task will migrate any new messages added to Chats after completing a Discovery task.
  • When the migration is complete, you must remove the Azure AD administrator account from the target tenant. As a result:
    • You can migrate a Chat only once, and the Chat cannot be re-migrated.
    • You cannot migrate new messages added to the Chat in the source tenant after the migration.

The Discovery Task will list all user accounts that have a Teams Chat. If new users are added to the source tenant after the Discovery Task completes, you must re-run another Discovery task
