Speed up Exchange 2010 move request

In CAS server navigate to c:\Program Files\Microsoft\Exchange Server\V14\Bin\MSExchangeMailboxReplication.exe.config file.

By default, the CAS servers are set to:

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

You can change the settings to:

MaxActiveMovesPerSourceMDB = “15″    
MaxActiveMovesPerTargetMDB = “15″    
MaxActiveMovesPerSourceServer = “50″    
MaxActiveMovesPerTargetServer = “40″    
MaxTotalMovesPerMRS = “250″

Once changed you must restart the MRS service.

Migration process is very disk I\O intensive!
