I have in the last couple of weeks started upgrading our exchange 2010 environment to exchange 2013. Upgraded the domain first from 2008r2 to 2012.
Then installed my first exchange 2013 server and configured.
Managed to get all the linkages working through the exchange 2013 frontend back to the exchange 2010 servers.
Owa, ActiveSync and other services are working correctly.
Mail flows from one system back to the other and the reverse.
Created a new account on 2013 and this is also working successfully.
Exchange 2013 CU2
Exchange 2010 SP3
Let it bed in for a few days and then started to work on migrating the mailboxes.
This is where I come across errors.
If I use the EAC, I get the error saying that "The mailbox of user that is located on a server that is running version 14 can't be opened on a server that is running version 15"
If I run the New-MoveRequest command from the EMS, the command runs successfully, but then, doesn't actually complete. The Get-MoveRequestStatistics always shows queued and no 0%
The event log shows it starting but not finishing. I even waited a few days to see
I have tried different mailboxes. Also confirmed that the Schema has been updated correctly. Tried researching and confirming setting but I seem to have them correct.
Any assistance in nutting this out is appreciated.
