Increase number of mailboxes transfering Exchange 2010

I was migrating a SBS 2003 server over too SBS 2011 over the weekend and when it came to migrating the Exchange information store over to Exchange 2010 it was only doing 2 mailboxes at a time, at that rate it would take the rest of the week just to move emails.
 
However this can be changed on your CAS server ours was SBS so its all on one box, navigate to the following location.c:\Program Files\Microsoft\Exchange Server\V14\Bin\MSExchangeMailboxReplication.exe.config
 
and edit in notepad

The default values are as follows

MaxActiveMovesPerSourceMDB = “5″   
MaxActiveMovesPerTargetMDB = “2″    
MaxActiveMovesPerSourceServer = “50″    
MaxActiveMovesPerTargetServer = “5″    
MaxTotalMovesPerMRS = “100″

I changed my values to

MaxActiveMovesPerSourceMDB = “10″   
MaxActiveMovesPerTargetMDB = “10″   
MaxActiveMovesPerSourceServer = “50″   
MaxActiveMovesPerTargetServer = “40″   
MaxTotalMovesPerMRS = “250″

After you have made these changes restart the Microsoft Exchange Mailbox Replication Service after you refresh you move request window you should see 10 mailboxes moving at the same time.
