I am trying to migrate from Exchange 2007 to 2013. There are about 50 mailboxes in the organization. I successfully moved the first 12 or so but no more will move. I'm using the web console to initiate the moves and the shell to monitor them. When I do a move the status is Queued. I stop and restart the MS Exchange Mailbox Replication service and the status goes to InProgress but nothing more happens. I waited on a few small mailboxes many hours over the weekend and they never go beyond InProgress. I don't believe its a single afflicted mailbox as I've tried several different mailboxes one-at-a-time. I've tried stopping and restarting the MS Exchange Mailbox Replication service and I've restarted both servers.
The old server has SP3 and RU10. The new server has CU2.
Thanks for any ideas.
