nt 4.0 and new win 2k3

Discussion in 'Server Migration' started by Corey Patterson, Jun 17, 2004.

  1. I have a windows nt 4.0 domain with 1 PDC and two BDC's and exchange 5.5
    running in DOMAIN. And 2 win 2k3 server both dc's running in DOMAIN2.com,
    one I that I am going to install exchange 2003 on. In the win2k3 domain I
    receated all the users and groups already.

    I want to know if what I'm planning will work.

    I want to down the NT 4.0 PDC and rename the Windows 2k3 server to
    DOMAIN.com. Is the exchange 5.5 server going to be able to allow users to
    logon to their mailboxes after everything is running and are the NT 4.0 BDC
    going to cause any logon problems once restarted.

    Thanks for any help.

  2. Hi Corey,

    You will get problem even you use same domain name. In fact, SID of user
    accounts and other objects are still different.

    As for your scenario, we can use the following method:

    1. Perform a full backup for the existing Windows NT PDC.
    2. Install Windows NT 4.0 BDC on the new server and apply the latest
    Service Pack.
    3. Promote the BDC to PDC.
    4. In-place upgrade the new server to Windows Server 2003.
    5. Install Exchange 2003 on the new PDC.
    6. Move the mailbox from the Exchange 5.5 to the Exchange 2003

    If you have more concern regarding the Exchange part of the upgrade
    project, I would like to suggest that you post the question in the
    following news groups:


    You can get more efficient and useful information regarding Exchange
    questions there.

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