  • Microsoft Exchange 2010 and 2003 together

    Hello I am having a small issue with my MS exchange 2010 and 2003
    Exchange 2010 has installed correctly without any issues.
    When I go into my management shell I can see all my users. They all have legacy mailboxes.
    When I right click on the user to migrate their mailbox to the 2010 server it cannot find my exchange 2003 server.

    When I go into my exchange 2003 I cannot see my 2010 server.
    I see the following (see pictures)

    jpg images

    I'm fairly certain that they servers can't see each other because they are in different containers. How do I make my servers see each other so I can migrate my mailboxes to my exchange 2010 server?


    Some additional info.

    My exchange 2003 has a front and backend.
    During my exchange 2010 install I didn't do anything special I just installed it and it installed correctly without any issues.
    Disregard the ex2k10 because it does not exist anymore. Bes is the correct exchange server

    Microsoft will provide you a detailed, step-by-step migration guide. Just go through the assessment and it will give you the proper steps:
    http://technet.microsoft.com/en-us/e...2013/Checklist

    Hint: start by selecting on-premises.

    But there might be some cleanup that needs to happen first. Is the EX2K10 box still around and can you uninstall Exchange from it?

      You don't use Exchange 2003 tools to migrate users to Exchange 2010. You need to use Exchange 2010 tools.

      The screenshot you have shown is perfectly normal and expected. Exchange 2010 goes in to another admin group. DO NOT attempt to move it, or remove that admin group.

      The server that doesn't exist any more will need to be cleaned up. There is no manual method to do that - you should recover that server so it can be removed correctly.

        Sembee, the server does exist but I uninstalled Exchange 2010 from it. I reinstalled Exchange 2010 on another (BES) server because I thought it might have been an issue with the Exchange server.

        What tools do I need to migrate the users from 2003 to 2010 where can I get them?

        Thanks!

          Did the uninstall complete successfully? If you have uninstalled the server then it shouldn't be listed in the Exchange Management Tools or in Exchange 2003.
          Have you restarted any servers since removing that server?

          You don't need any additional tools to migrate users, it is all done with native tools. Are you following any guides on migration? Everything (and I mean everything) is documented on TechNet.

            It actually did uninstall successfully. No errors nothing. The actual server is still alive but the installation of EX10 is still visible. The database is gone though in the new EMC I don't see the database anymore but I still see the Exchange server name.

            You wrote you need exchange 2010 tools. I assume you mean in the EMC when I go to the user mailboxes I right click on them and go to local move.

            When I do that it tells me it cannot find the server where the user mailboxes are stored (my exchange 2003 server)
