receiving emails during exchange 2007 to 2010 migration RRS feed

  • Question

  • We are about to start a migration from 2007 to 2010, we are trying to determine if best to do this during work hours or only after hours. Our biggest concern right now is when a user is in the middle of being moved, what happens when that user is sent email? Will they receive it? if they will receive it, is there a delay? or have to wait till the move is complete? We are in cached mode.

    Thanks

  • New messages during the move will continue to get delivered,  when the mbx is locked it will sync the data to the target mbx. During this lock new messages wont be delivered but queued. http://blogs.technet.com/b/exchange/archive/2010/07/19/3410438.aspx

  • Hi

    You can run in coexistence and create routing connectors etc. for mail to flow between the 2 platforms while you perform the mailbox moves. The move process is performed online, and end-users will be able to access their mailboxes during the move.

  • 2007 and 2010 HUB Transport serverswill accept the email  and will deliver the email when the mailbox is ready to accept emails. There won't be any loss of email.

  • yes not worrying about losing email, I understand mail will still be accepted.

    my concern is this:

    My mailbox is in the middle of being moved (2007-2010), someone sends me an email.

    When will i see that email? During the move or after the move?

    this is what will determine if we can do moves during the day or after hours

    I hope this clears things up a bit

  • hi,

    Answer your question, during the move you can see your email, but not whole process, the last couple of minutes of the move, the mailbox will be locked and the users can't access their mailboxes at that time.  And you should note that your exchange version should be exchange 2007 sp2 later, then you can use the online move feature.

    These are some sentences in Microsoft document:

    If the mailbox database are Exchange 2007 SP2 or Exchange 2010 then moves will be online. When the move is complete the mailbox will be unlocked and the user will have to close Outlook and reopen Outlook. The Outlook client will be updated with the new mailbox server location and the user will then be able to access their data.   

    And if you have many mailboxes, mailboxes migration will need more bandwidth and will in a long time, this will affect your network using.

    So I recommend that you should do that after hours.

    hope can help you

    thanks,

    Thank you this is what exactly I was looking for. I know how the migration worked and will be locked. I just wanted to know when new mail would be delivered. Thanks for the straight answer
