We are moving mailbox from Exchange 2007 to Exchange 2010. We are using Exchange Console, Local Move Request to move the mailboxes to Exchange 2010. The problem is, the move is too slow. After 4 days we only manage to move 1400+ mailboxes. We have 4950 mailboxes, the overall database size is 640 GB.
We changed the value MaxActiveMovesPerTargetMDB in CAS from 2 to 25 and restart the server. Even after we restart the server, the CAS still move 2 mailboxes simultaneously.
We have 1 CAS, 2 Mailbox role with 1 DAG. Our CAS is running in Hyper V.
We are running Exchange 2010 SP1.
