Commenced a full O365 migration without success

On one of my sites, I commenced a full O365 migration. SO far, many of the mailboxes were moved successfully and without any issues. Trouble started with one batch, where I got Azure AD failure when migration was complete (or incomplete if you will). This is the error message I am getting right now:

“Warning: The following failure occurred after the Active Directory modification completed: The domain controller ‘SN1PR16A001DC06.NAMPR16A001.PROD.OUTLOOK.COM’ is not available for use at the moment. Please try again.”

What might be the cause for this, especially if other batches were ok?
