Speeding Up Exchange 2010 Mailbox Moves
1Performing Mailbox moves in Exchange 2010 can be a rather slow process, moving at 3-4GB an hour. If you’re migrating a large store this is a long period of time to wait. Here’s how you can speed up the process significantly. I’ve used these settings on several SBS 2003 to 2011 swing migrations including from a 2003 swing server running in Hyper-V on a SATA drive. If you’re moving from something beefier than that I would suggest bumping up the MaxActiveMoves settings accordingly.
On the server you’re migrating to edit MSExchangeMailboxReplication.exe.config located in your Exchange bin folder (by default: c:\Program Files\Microsoft\Exchange Server\V14\Bin)
Find the following default values:
MaxActiveMovesPerSourceMDB = “5″
MaxActiveMovesPerTargetMDB = “2″
MaxActiveMovesPerSourceServer = “50″
MaxActiveMovesPerTargetServer = “5″
MaxTotalMovesPerMRS = “100″
Change them to:
MaxActiveMovesPerSourceMDB = “7″
MaxActiveMovesPerTargetMDB = “7″
MaxActiveMovesPerSourceServer = “50″
MaxActiveMovesPerTargetServer = “40″
MaxTotalMovesPerMRS = “250″
Restart Microsoft Exchange Replication Service
Nice work, helped me out big time..
