2010 mailbox move

magapie asked
Last Modified: 2012-05-10
I have a 2003 and 2010 server. Performing a mailbox move is quite a time consuming experience. I first thought that the mailbox was too big. So I picked a smaller one of 1.75 gb. It gets to 25% and stops. There's a gig switch between the servers. I'm not sure why it takes so long and/or fails.
Watch Question

where are actually performing the mailbox move?  you should use Exchange 2010 to do the actual move, by creating a move request.

You need to pull to Exchange 2010 and not push from Exchange 2003

I have done quite a lot of 2003 to 2010 move and they fly

I'm in 2010 pulling the old mailbox over. Right now it's been 8 hours and only 61% complete on a 1.76gb mailbox.
Magapie - are you using local disk storage on both Servers?  If so, this is def your problem.  The GB link speed is not going to matter, it is all about disk i/o.  If you are using SAN's you would be getting those 2GB mailboxes finished in under 20 minutes.  Of course, this point assume you are using local storage.


Well this is a small office and there is no san. These servers are not under any i/o stress.
It is not the "stress" factor, it is literally the speed of the SAS drives and/or configuration.  Such as what RAID, what kind of drivers, speed of drives etc.

I would run Perfmon while you're moving a mailbox and look at your disk I/O counters.  I bet you that will tell you more than anything.


I skipped using 999 and it still stalls out. It's not a san issue. I deal with disk i/o all day long. If it was the disk it would just be slow. This is stalling out at 25%. Is there a verbose logging or error log?


Those are good articles. The performance issue has more to do with moving multiple mailboxes. I'm just trying to move one at a time. it stops on 25% then takes hours to finish.

As you can see it is crawling.
Damm that is really slow, assume the nework between 2003 and 2010 is good?

On a LAN i have been getting upto 100MB/sec
did the move complete? How long did it take?
was any of the information useful? do you want to award points and close?
