Dual Migration to 2003

    We are consolidating two domains into 1 domain. Currently
    we have two DCs lets call them C3P0 and R2D2. They are
    both Win 2000 domains. On a new server ATST, we are
    running Server 2003. We want to migrate C3P0 to ATST and
    then also migrate R2D2 into C3PO. So in the end we'll
    have one domain C3P0 on a new server ATST. Is this
    possible, or will there be global catalog conflicts? If
    it is possible could someone explain the steps.
    Appreciate it.

  2. Tyler-

    If I'm reading this correctly, it doesn't make any sense to me.

    Setup a new domain (ATST). Use the ADMT tool to collapse the two existing
    trees into ATST.

  3. Hi Tyler,

    Thanks for your posting here.

    What is your finial purpose?

    Just like Brian said, if you want to migrate C3P0 and R2D2 domains to ATST
    domain, you can use ADMT tool to perform migrations in ATST domain.

    It will not cause any conflict.

    Let me clarify. C3P0 cannot go offline or hundreds of
    users will be inable to login. We want to transfer C3PO
    domain to ATST server, so no one can tell the switch has
    occurred.

    If I understand what you folks are saying then I should
    join ATST to the C3P0 domain, set it as a secondary DC
    and replicate to it, then promote it to a Primary and
    migrate R2D2 into it???

  5. No.

    None of you rdomains will go offline.

    ATST is your new AD domain, right?

    Using the ADMT tool, migrate the C3PO domain to ATST. You may wish to create
    an interim OU called C3PO and drop everything from it in there for the
    interim.

    Once this is all happy happy, repeat the process with R2D2.

    This is a two step process. Don't migrate R2D2 to C3PO and hten C3PO to
    R2D2. GO straight from the sources to the new domain.

  6. Hi Tyler,

    Do you mean ATST is just a server not another domain?

    If so, you can join the ATST server to C3P0 domain and promote it to be a
    Domain Controller. So it will also keep a copy of the database of C3P0
    domain.

    When you migrate R2D2 domain into the C3P0 domain, the data added will
    replicate to every DC in the C3P0 domain including ATST server.

    Wish it helps.
