Restore to Exchange 2003 Server when on Exch 2010
Posted on 2012-08-15
We're are about to complete the process of migrating to Exchange 2010 from Exchange 2003. The last step is to decommission the 2003 server. A question came up about being able to restore 2003 mailboxes from tape. From what I understand, you can't restore an older 2003 mailboxes into the 2010 environment. We use Symantec BackupExec 2010 R3 for our backup solution and there appears not to be an option to do this. I'm trying to figure the best way to be able to recover backed up email and go native with Exchange 2010.
One thought would be to promote the 2003 server to a DC, point exchange/active directory services to itself and the isolate it from the network and then do DC failure cleanup to our AD site. Anything I should consider when doing this?
Has anyone come across this issue?
Thanks in advance for your assistance.
