Solution 1Recommended

Configure Automatic Completion in the Exchange Admin Center

Use the Exchange Admin Center to manage batch settings and set the migration batch to finalize automatically.

You can configure a migration batch to complete automatically or schedule it for a specific time depending on your organizational needs. This is particularly useful for hybrid remote move migrations where the final synchronization needs to happen seamlessly during off-hours.

1
Access the Exchange Admin Center

Log in to the Microsoft 365 admin center using your global or exchange administrator credentials, then navigate to the Exchange Admin Center (EAC).

2
Open the Migration Dashboard

In the EAC, go to the 'Migration' tab or dashboard to view the list of your active and completed migration batches.

3
Select the Target Batch

Click on the specific migration batch you want to configure. This will open the details pane for that particular batch.

4
Set the Completion Method

Locate the completion options. Select 'Automatically complete the migration batch' or specify a specific date and time for it to complete automatically, then save your changes.

Migration Type Constraints: The available completion options may vary based on the type of migration you are running (e.g., Staged, Cutover, IMAP, or Hybrid remote moves).

Frequently Asked Questions

Can I schedule a migration batch to complete at a specific time?

Yes, within the Exchange Admin Center batch settings, you have the option to automatically complete the migration batch after a specified time. This is ideal for scheduling the final synchronization during weekends or specific maintenance windows.

Why is the option to automatically complete the batch missing?

This option might not be available depending on the type of migration you are performing (like an IMAP migration, which simply syncs email and doesn't 'complete' the same way a hybrid move does), or if your admin account lacks the required Exchange permissions.

Does an automatic completion instantly switch routing for users?

In hybrid remote move migrations, completing the batch triggers the final synchronization and mailbox switchover. Once completed, the user's active mailbox is officially transitioned to Exchange Online, and mail routing is updated accordingly.
