  • Migrating to Exchange 2003 in a Windows 2000 Domain

    Hello,

    We have a customer running a Windows 2000 domain with (2) domain controllers one of which is running Exchange 2000.

    They've bought a new Windows 2003 Server and are looking to migrate to Exchange 2003.
    If the Windows 2003 Server is a member server of the Windows 2000 domain does Adprep need to be run on the Windows 2000 domain controller or will the exchange 2003 installation process handle any changes to the AD Schema.

    I have read multiple documents and threads and adprep seems to refer to AD issues when adding a Windows 2003 Domain controller.

    Are there issues when adding a Windows 2003 Server to run Exchange 2003 in a 2000 domain.

    Thanks in advance

    Is the new exchange server going to be a AD controller ? You will need to run the adprep utility either way on all the 2000 servers, since you are dealing with a new os.

    This process is really pretty straight forward, I have done it dozen's of times to my clients. The mailbox move as well it pretty painless. Profesionally I have done this task on site at clients in about 6 hours ( with about 50 mailbox's in the system ).

    You might have the reboot the Windows 2000 AD servers once you complete the ADprep on them, so just be aware of this. Also during the mailbox move the mail stores will go down, this is likely best done after hours for the client.

    Questions, just post back and i will respond.

      Hi Rob,

      Thanks for the quick response. The new 2003 Server will be a member server and not a domain controller. Is ADprep still required in this scenario?

      Thanks

        Yes (if i am not mistaken) ad prep is still required due to the fact that Exchange 2003 will need to write 2003 based objects back to AD.

        I don't have a lot of clients who use Exchange 2000 anymore at this point, so the specific details are a bit fuzzy. If memory serves me right, you do.

        I have found that following the step by step install guide on exchange to be very helpful ( shocking for ms ).

          Hi Rob,

          That is where my confusion came about. I followed the exchange deployment services (in the lab). It talked about forestprep and domain prep. I do not remember seeing anything about adprep.
          Adprep came about after I was searching on Google. Again, it seemed to refer to a Domain controller, hence my confusion.

            Looks like there is some confusion over prep here.

            If you are installing Exchange 2003, then you need to run forest prep and domain prep from the Exchange 2003 CD.

            You only need to run adprep if you are going to install a Windows 2003 domain controller in to the domain. It is not required if you are installing ONLY Exchange 2003.

            Basically put the CD in and follow the prompts for your scenario. It will tell you what needs to be done.
            Once Exchange is installed, service pack it and then get the updates for Exchange from Microsoft Update.
            If you have installed Windows 2003 SP2 on to the machine (or it comes with it) you will get a compatibility prompt. Just accept it and move on.
            Finally if you need a guide to move to the new server, mine is here: http://www.amset.info/exchange/migration.asp
