    Greetings,

    I need your help/consultation, here is the scenario:
    We are a midsize/small network with about 200 users, running AD with five
    DC’s and a PDC in five different physical locations. Moreover, PDC and a DC
    are located in the same branch where the core of the network is located (a DC
    for each Brach). We are running Exchange 2000 on the PDC. I was asked to
    upgrade the network to Windows 2003 AD and Exchange 2003.

    I was given only one new server to replace the PDC(since it is an older
    box). I need to use the existing servers for the rest of the migration. So, I
    need to move the PDC and Exchange to the new 2003 box running Exchange 2003
    eventually.


    My plan was to install Win 2003 on the new serves and promote that server to
    AD and then install Exchange2003 and then move the old PDC to that box.

    Step 1. run forestprep/ adprep and domainprep /adprep
    Step 2. Promote the new 2003 server to AD
    Step 2.5 upgrade existing exchange 2000 server to 2003
    Step 3. Install Exchange 2003 on the new server, which is now a new DC
    Step 4. Move the mail boxes form the existing Exchange server which is
    running on the old PDC to the newly introduced Windows 2003/Exchane 2003
    server
    Step 4.5 Uninstall Exchange from the old PDC and reroute the incoming emails
    to the new server.
    Step 5. Move PDC to the new server
    Step 6. Demote the old PDC and take it off the network
    Step 7. upgrade the rest of the 2000 DC to 2003 DC

    Now here are my questions:

    Q 1. I am wondering if it is a good practice running Exchange 2003 on the
    same box that is PDC or DC?

    Q 2. What will happen when I want to install Exchange 2003 on the newly
    promoted 2003 DC while another Exchange server is running on the same AD (on
    the old PDC)?

    Q 3. What is the easiest way to tell Outlook clients to download messages
    form the new server? Can it be mixed? Some form the old exchange and some
    from the new server.

    Q 4. Can I run both Exchange servers parallel for a short period of the time
    and set the new Exchange server to be the front head and then it
    replicate/sink with the old exchange server for the duration of the client’s
    migration?

    Q 5. Is there a better/smarter way to do this migration?

    I thank you a head of time for any suggestions and recomandations to any
    part of my question.

    Have a happy holiday,

    Essi

  2. Hi Essi,

    Thanks for your posting here.

    However, this is a newsgroup mainly discussing operating system migration
    issue. For the Exchange migration issues, I would like to suggest that you
    submit a new post in our Exchange news groups:

    microsoft.public.exchange.admin
    microsoft.public.exchange

    The reason why we recommend posting appropriately is you will get the most
    qualified pool of respondents, and other partners who read the newsgroups
    regularly can either share their knowledge or learn from your interaction
    with us. The above newsgroups are dedicated for discussing Exchange issues
    and I believe that you will get more specific and detailed suggestions
    there.

    By the way, I believe the following documents will be helpful:

    278888 How to associate an Exchange 2000 mailbox or an Exchange 2003 mailbox
    http://support.microsoft.com/?id=278888

    Moving Mailboxes in Exchange Server 2003
