Exchange 2010 to Exchange 2013 Mailbox Move

Hi All,

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.

When you execute Get-ExchangeServer on Exchange 2013 Powershell. Are you able to see both server?

Yes I do.
I see the two current servers running version 14.3 and the new one running 15.0

Any other thoughts?

Hi shreedhar,

I have gone through this document and had followed these steps originally.  Along with the official MS documentation.
Unfortunately, this has not resolved the issue.

Thanks for looking and do you have anything more?
Shreedhar EtteCommented:
Please run New-MoveRequest and -Verbose at the end.

Post the output.

I have attached the screen shot.
Removed all the identifying information only.

Shreedhar EtteCommented:
- It does show any error.
- What is mailbox size of recruitment?
- Are there any errors in the event log of both exchange servers?
- Please execute move request with -WhatIf and post the output
- Also run exchange 2010 best practise analyser tool and if any error reported post it.

Hi Shreedhar,

OK, this is now fixed.

Tried recreating the migration mailbox as well.

The issue had nothing to do with the commands or the mailboxes.  In reviewing the setup, I noticed that ALL of the system mailboxes were on the exchange 2010 servers and none on the exchange 2013 servers.  I can't tell you why.
After the Arbitration mailboxes were moved to 2013, all the moves that had been queued went through.
Also tried some other mailboxes and these moved correctly as well.

Thanks for the assistance
