Exchange 2003 to 2010 Mailbox Move

Hello Everyone,
 
         We recently implemented Exchange 2010 servers in our org.  When I try to move mailboxes form 2003 to 2010, only 2 mailboxes are moving at the same time.  I had read that you could move 5 simultaneous mailboxes at the same time, however it only allows me to run 2.  Is there a setting I need to change on the server to allow me to run 5?

Thanks!
Ash

Pull open Notepad. If you have UAC enabled, be sure to Run as Administrator. Browse to the install location of Exchange and open the following file:

C:\Program Files\Microsoft\Exchange Server\V14\Bin\MSExchangeMailboxReplication.exe.config

Find the following line:
MaxActiveMovesPerTargetMDB = "2"

The default value (as of SP1, version 218.15, at least) seems to be 2.

Change the 2 to a 5, or an 8, or whatever you’d like it to be.

MaxActiveMovesPerTargetMDB = "5"

Review the other settings to make sure they reflect what you’d like to see in your environment, and to ensure you’re not getting throttled on any other setting that may pertain to what you’re trying to accomplish.

Save the file, and restart the Microsoft Exchange Mailbox Replication service.

Great, thanks for the reply.  So, changing it to 5 should not affect any performance should it?

Moving 5 mailboxes as opposed to 2 will definitely affect I/O peformance.  The question is whether or not your server is robust enough that the performance impact will be noticable or not.  Try it and if it's too slow then back it down to 4 or 3 if necessary.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

The ex2010 servers are extremely powerfull, however the ex2003 server is not the best performing server.

There's no way to give a definitive answer, the only way to really know is to try it.  Maybe it would be best to test after hours?
