    Dear,
    I am planning to migrate from winnt4.0/exch5.5 to Win2003/Exch2003 and i
    will follow this procedure from Bob
    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

    My question is : after point 3 : " Promote the BDC to PDC.
    4. In-place upgrade the new server to Windows Server 2003" , is the old
    PDC now BDC
    will stay on the network or i must remove it form the network.
    After upgrading to W2K3, the exchange server 5.5. will continue to work on
    the BDC or i need to install the same day Exchange 2003 and move the
    mailbox.
    Which option should i choose when it comes to install the active directory :
    - create a new forest? - create a child domain or create a domain tree in
    existing forest.
    What about DNS, do i need to install before upgrading to Win2003 DNS on the
    PDC?
    I don't want change the domain name.
    Actually the domain name is : CSL but i think in windows 2003 i will need to
    put something like CSL.CO.ZA for DNS to work properly
    Please Help
    Regards
    AIME

    Dear,
    Today , i finished the upgrade
    ( Install Windows NT 4.0 BDC on the new server , Promote the BDC to PDC.
    In-place upgrade the new server to Windows Server 2003.)
    There is no error in the event viewer on the new DC W2k3, but in the BDC i
    found the event id 5723.
    In Next stage, i would like to install Active directory and Exchange server
    2003
    My questions are :
    1- The DHCP,WINS and DNS are in the BDC, how can i move them on the new W2k3
    DC?
    2- Which option should i choose when it comes to install the active
    directory :
    *create a new forest? * create a child domain or create a domain tree
    in existing forest.
    I would like to keep the same domain name CSL, but with active
    directory i don't think it will work
    if not, the name like mypc.csl.co.za will be good?
    3.When can i demote the BDC so that in can use the DNS,DHCP,WINS from the
    new W2k3 DC?
    I appreciate a lot your help
    Regards

  3. Hi AIME,

    Thanks for your posting here.

    1 You can install DNS service on Windows 2003 server and create a secondary
    zone, then transfer the zone over to the Windows Server 2003 DNS. Change
    the secondary zone on the Windows Server 2003 system to a AD-Integrated
    Zone.

    Reference:
    814591 HOW TO: Install and Configure DNS Server in Windows Server 2003
    http://support.microsoft.com/?id=814591

    As for WINS, please refer to the following article:

    300473 HOW TO: Migrate a WINS Database from Windows NT 4 Server to Windows
    2000
    http://support.microsoft.com/?id=300473

    As for DHCP, we can move DHCP database per the following article:

    325473 HOW TO: Move a DHCP Database to a Computer That Is Running Windows
    http://support.microsoft.com/?id=325473

    2 Based on your description, you can use a new DNS name and keep the
    original NETBIOS domain name. So I would like to recommend that you choose
    "create a new forest". If your old domain name is "CSL", you can choose
    "CSL.CO.ZA" as new DNS domain name when you upgrade PDC. The NetBIOS domain
    name is still "CSL". There is no conflict between DNS name and NETBIOS
    name.

    The Domain Name System (DNS) is the Active Directory locator in the Windows
    2003/2000 domain. Active Directory clients and client tools use DNS to
    locate domain controllers for administration and logon. NetBIOS name is
    used in the Microsoft Windows NT version 4.0-compatible Locator (for
    example, WINS).

    3. You can try these steps to demote the NT BDC.

    1 Upgrade the BDC to Windows 2000/Windows 2003. Do not cancel the DCPROMO
    process.
    2 Once DCPROMO has completed, run DCPROMO again to demote the server to a
    member server.

    In addition, there is a third party tool, UPromote which can downgrade your
    NT BDC domain controller to a standalone server easily.

    Hi Bob,
    Just a small question about the procedure :
    How can I proceed to install all the services correctly :

    Install Active directory
    Install DNS
    Migrate DHCP from Nt4 to W2k3
    Migrate WINS from Nt4 to W2k3
    Install Exchange 2003
    Move mail boxes.
    Upgrade the old BDC tol W2k3 + DCPROMO then Demote it
    Demote the BDC
    Is it a correct order?


    Thank you

  8. Hi Aime,

    I would like to suggest that you migrate WINS server first, then when you
    migrate DHCP, you can set the server option to assign the new WINS server
    to the clients.

    I believe the following documents will be helpful.
