I'm trying to move mailboxes from 2010 to 2013, but I'm experiencing a lot of issues.
My move batches keep hanging (stalled) for minutes and hours on end, and I can't seem to keep them going consistently.
I have two DAG's, one for Archive boxes, and one for Primary mailboxes. Each DAG has three members with DB copies of each DB. The npdes and the clusters themselves are up and healthy. However, at random some of the DB's Content Index state will go to Failed or SuspendedandFailed. At which point I force a catalog refresh and DB index update, and it goes to healthy.
I've created the "ContentSubmitters" AD group (and assigned it permissions), reset the Search and Host controller services on each server, and restarted the Replication service. I also deleted and recreated the Index for each DB prior to restarting services. No dice. I've also already moved the system mailboxes over to the 2013 databases.
I'm also getting some "Transient" errors in the user move log, things like this:
Transient error ResourceUnhealthyException has occurred. The system will retry" 5/4/2014 8:43:55 AM [exmb1] The job encountered too many transient failures (60) and is quitting. 5/4/2014 8:43:55 AM [exmb1] Fatal error ResourceUnhealthyException has occurred.
Error: MigrationPermanentException: Warning: Target mailbox unlock operation was not replicated. If a lossy failover occurs after the target mailbox was unlocked, the target mailbox could remain inaccessible. Error details: The store ID provided isn't an ID of an item. --> MapiExceptionNetworkError: Unable to open entry ID. (hr=0x80040115, ec=0) Diagnostic context: Lid: 45025 Lid: 45345 StoreEc: 0x80040115 Lid: 22894 Lid: 24942 StoreEc: 0x80040115
Any ideas would be appreciated!!!
