Remigration

To remigrate messages, planner tasks and files, start a new teams migration task and follow the steps outlined in Migrating Teams. Select whether to migrate messages with attachments from the various options.

 

NOTE:

  • Do not reuse a previous migration task because the task options you need may be different.
  • See What We Migrate to review the Teams objects that are supported.
  • An incremental query is used automatically to find messages, tasks and files that were added or changed.
  • The initial synchronization must have completed successfully for the incremental synchronization to succeed.
  • Perform a remigration before you switch from the source to the target tenant.
  • Do not delete teams in the target tenant after migration.

 

Messages

Messages that were previously migrated successfully will not be remigrated. Messages are remigrated as follows:

  • New messages that are added since the last synchronization will be migrated.
  • Messages that were partially migrated, for example the attachment was unavailable during a previous migration, will be migrated. Updates to these messages by users in the target tenant will not be overwitten.

Planner Tasks

Planner Tasks in the target tenant that are created or updated will not be impacted. Planner Tasks from the source tenant will be remigrated as follows:

  • Previously migrated Planner Tasks that are updated on the source tenant will not be migrated to the target tenant.
  • New Planner Tasks will be migrated to the target tenant.

Files

Previously migrated list items and files with the same name and ID will be remigrated from the source tenant as follows:

  • Updates on source will be migrated to the target.
  • Updates to target will be overwritten by the remigrated source items or files.

When Teams files are remigrated an incremental query retrieves files that have been added or changed in the channels since the last synchronization. Follow the steps outlined in Migrating Teams and select Migrate messages and files.

Mapping, Renaming and Merging Manually from a File

To rename Microsoft 365 groups or merge one or more source groups to a specific group in the target tenant, a CSV file is used to indicate the mapping between source and target groups as described below.

To creating a mapping file:

  1.  Prepare a comma-separated values (CSV) file with the source and target group names.

    TIP: Export selected groups to a comma-separated values (CSV) and then edit this file. See Exporting Groups for more details.

  2. The header row defines the names of the source and target attribute used for mapping. Subsequent rows list the mapping values of the attributes.

    The columns are as follows:

    • Source Mailnickname - unique name of the source group. The following column header variations are supported: SourceMailNickname, Source MailNickname, Source MailNickName. The column header is case sensitive.
    • Target Mailnickname - unique name of the target group. The following column header variations are supported: TargetMailNickname, Target MailNickname, Target MailNickName. The column header is case sensitive. You can merge multiple source groups to a single target group when you specify the same Target Mailnickname in a mapping file.
    • Target Group Name - display name of the target group. The column header is case sensitive.

    Example 1: Row 2: Simple change of name.

    The source group display name and mailnickname are changed.

    Example 2: Rows 3 and 4: Different target groups with the same display name.

    The Target Mailnicknames are different but the Target Group Names are the same. The Target Mailnickname takes precedence and the groups will be mapped to distinct target groups but the display name of each target group will be the same. It is recommended that you use unique display names to avoid confusion.

    Example 3: Rows 5, 6 and 7: Merge multiple source groups with the same target group.

    The Target Mailnickname is the same. The source groups will be merged with the same target group with the specified display name.

  3. Save the CSV file.

NOTE: File names with non-ASCII characters are not supported.

To upload a mapping file:

  1. Log in to Quest On Demand and choose an organization if you have multiple organizations.
  2. From the navigation pane, click Migration to open the My Projects list.
  3. Create a new project or open an existing project.
  4. Click Teams from the project tiles, or click Open from the Teams tile to open the Teams dashboard.
  5. Click the M365 Groups tab.
  6. Click More Actions and then click Map from File. The New Mapping from File Task wizard opens.
  7. Step 1: Mapping file
    1. Click Browse and select the CSV mapping file. The selected file name appears next to the Browse button.
    2. Click Next.
  8. Step 2: Notification
    1. Send notification email once the task is completed - select this option to send a notification email when a mapping task completes.
      • Only in a case of failure - select this option to send the email if the mapping task fails to complete successfully.

Discovering Chats

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

Managing Chats with Collections

Migrating large numbers of chats requires careful planning. Organize the user accounts into collections to make large chat lists more manageable.

Adding chats to Collections

You can add user accounts with chats to collections in three ways:

To add selected user accounts to a new collection:

  1. From the project dashboard, click Open in the Teams tile to open the Teams workspace.
  2. Open the Chats tab and select the user accounts that you want to add to a collection.
  3. From the actions toolbar, click New Collection. The New Collection dialog opens.

  4. Enter a collection name in the Collection name field and click Save to add the selected user accounts to the collection.

To add selected user accounts to an existing collection:

  1. From the project dashboard, click Open in the Teams tile to open the Teams workspace.
  2. If you need to create a new collection:
    1. From the top-right corner of the workspace, click Select Collection > + New Collection
    2. Enter a collection name and click Save to add this collection to the project.
  3. Open the Chats tab and select the user accounts that you want to add to the collection.
  4. From the actions toolbar, click Add to Collection. The Add to existing collection dialog opens.

  5. Select your collection from the Collection name dropdown and click Save to add the selected user accounts to the collection.

To create one or more collections with a CSV file:

This is a two-step process as described below:

Step 1: Prepare the CSV file

NOTE: Using a CSV file provides the following additional benefits:

  • Multiple collections can be created with the same CSV file.
  • Existing collections can be specified in the CSV file to add additional user accounts
  • Accounts can be listed in multiple collections

Use the format shown below to prepare the CSV file. The minimal set of columns required are shown.

TIP: You can export the selected user accounts to a CSV file and then add the Collection column and retain the Source UPN column. All other columns in the exported CSV file will be ignored so you can remove those columns if you want.

  • Collection - Column header for the collection name
  • Source UPN - User Principal Name (UPN) of the source account.

Step 2: Import the CSV file

  1. Log in to Quest On Demand and choose an organization if you have multiple organizations.
  2. From the navigation pane, click Migration to open the My Projects list.
  3. Create a new project or open an existing project.
  4. Click the Teams tile, or click Open from the Teams tile to open the Teams workspace.
  5. Open the Chats tab.
  6. From the actions toolbar, click More Actions > Import Collections. The Import Collections from File dialog opens.

  7. Select Chats from the Specify kind dropdown.
  8. Click Browse and select the CSV file. The selected CSV file name appears.
  9. Click Import.

NOTE: If a collection in the CSV does not exist, a new collection will be created with the name specified in the CSV.
