  • Disabling all user mailbox before manually migrating .EDB files to new server

    Hi All,

    I'm about to performs uninstall of my current MS Exchange Server 2007 (All in one role CAS HT MBX) and then copying manually the Exchange Server *.EDB (Mailbox Database) and also the transaction log if necessary into the new server which has got Exchange Serve 2010, but the problem is that I have to DISABLE all of the user mailbox, this is quite scary since I don't know what happened if I select all then right click and selecting disable all of the mailbox, would I still be able to copy the old exchange server 2007 email database into the new one and retaining the email content of all users in my company ?

    see the following error message duyring the server uninstall:

    Code:
    Summary: 4 item(s). 3 succeeded, 1 failed. 
    Elapsed time: 00:01:57

    Error:

    First question is why you want to walk on such an difficult migration path?
    This would only make sense if you built your new Exchange 2010 server on a complete seperate network with no connection to the old AD/Exchange installation.

    If your new Exchange 2010 server will be a part of your current AD/Exchange installation, just install it and migrate mailboxes the normal way.

      Ah yeah, so i can just join the Exchange Server 2010 and then join that as the organizational Mail Server (DNS MX records edit) and then go to EMC (on 2007) then Move-Mailbox DB ?

      yeah I didn't think of that.

        Basically yes, thats it, read on upgrading from E2007 to E2010, plenty of documentations on the web.

            What you originally planned to do wouldn't work anyway because of differences in the Exchange databases. In most cases you cannot use an Exchange database from one version with another. The only exception with that can be in the recovery storage group, but only within the same generation - so Exchange 2000 databases will mount in an Exchange 2003 RSG, but an Exchange 2003 database will NOT mount in an Exchange 2007 RSG.

            I am surprised you came up with that plan - did you not read the upgrade documentation on Technet? The upgrade procedure is heavily documented.

              Thanks Sembee, The initial plan is to have a direct cutover of MS Exchange 2007 - 2010 without having to install it side by side, but then it turns out to be the hardest thing to do.

                That isn't a supported migration/upgrade scenario.
                The only supported migration/upgrade scenario is swing.
