Question about Exchange 2007 database backup after migration to Exchange 2010 RRS feed

  • Question

  • Hello all, 

    I'm planning a migration from Exchange 2007 to Exchange 2010 for the company I work for. I have a question about Exchange 2007 database backups. Currently, we backup our Exchange 2007 databases daily on our Barracuda Backup appliance. My question is the following, can an Exchange 2007 database backup be restored on Exchange 2010? This question came to mind when I thought of the following scenario, let's say I finish moving all the mailboxes from Exchange 2007 to 2010 and a user asks me to retrieve some emails they deleted by accident, but the emails in questions are on the 2007 database backup. How would I go about restoring that mailbox from the 2007 database backup if I've already decommissioned my Exchange 2007 server. Is it possible to restore and mount the 2007 database backup on the Exchange 2010 server.

    If someone could shed some light on this matter or provide information, I'd appreciate it. Thanks!

  • No.  Exchange can only be recovered onto the version (and more often than not, the service pack version) of Exchange that was used to back it up.  So if you feel you may need to restore messages that were deleted on the Exchange 2007 server, you'd better keep that server around until you no longer need this fall-back.

  • You are right, you can't add an Exchange 2007 server to an Exchange 2010-only organization.  And yes, you can keep only the mailbox server - you needn't have CAS or hubs running on Exchange 2007 if there are no mailboxes on the server that you need to service.  If your Exchange 2007 server is a physical system, I'd even consider H2V so you don't need to have the extra hardware laying around.

    Now, if I was in your situation, I'd keep a virtual Exchange 2007 server for a month or so, and tell the users that if they need anything, now is the last chance to let you know.  Tell them again ten days before you decommission the server, then kill it.

  • Can I just keep the Exchange 2007 Mailbox Server or do I need keep both the CAS/HUB server and the Mailbox server if all I want to do is restore a database? I mean after I've completed the migration to 2010.

  • Thanks for replying!

    So my Exchange 2007 database backups will become useless after the migration is complete? I don't think it's recommended, or possible for that matter, to build an Exchange 2007 server after Exchange 2010 has been put in place just to restore a 2007 database, am I right in this assuming this?

    What you do if you were in this situation? Would you just tell the user the emails cannot be restored?

  • I think I will do exactly that. 

    Thanks for your infinite knowledge, Will! As always you are very helpful.
