Are you sure you want to complete the migration batch "CompletionABC"? There are 3 pending items that won't be migrated because the batch hasn't been restarted since the items were added.
Ignoring the warning and responding 'Yes' didn't seem to do anything thing. The CompletionABC batch remained in a 'Stopped' status.
However, the test in which I ran ‘Start-MigrationBatch’ after ‘New-MigrationBatch’ and before ‘Complete-MigrationBatch’ completed as expected.
What is the intent of the -DisableOnCopy parameter? I notice that that the original migration user remains in the original migration batch as an Error with the reason:
MigrationUserMovedToAnotherBatchException: The user was moved to a new batch
Which makes sense but I'd really like the option to remove the user from the original batch. In fact, I follow up with Remove-MigrationUser to clean things up. This is fine when using EAC but, if I want to use PowerShell, I need to target the GUID of the MigrationUser as the Identity/SMTPAddress now matches multiple MigrationUsers:
The operation couldn't be performed because '' matches multiple entries.
- The DisableOnCopy switch disables the original migration job item for a user if you're copying users from an existing batch to a new batch by using the UserIds or Users parameters. Reference https://docs.microsoft.com/en-us/powershell/module/exchange/move-and-migration/new-migrationbatch?view=exchange-ps
- This error MigrationUserMovedToAnotherBatchException is normal once we disable the migration user from the source batch and copied to another one.
- Removal of the Migration User from the Source Batch must be done manually, at least for the moment. This way we have a record of having moved them around. If you use PowerShell, then yes, as you mentioned, you need to specify an unique identifier of the migration user (remove-migrationUser -identity id) otherwise you get into this error "The operation couldn’t be performed because ” matches multiple entries.". It is maybe easier to remove the migration user from GUI.
