Migration Problem with Win2k & Win2003

Discussion in 'Server Migration' started by CLEY, Jun 19, 2004.

    We have one(1) existing Domain Controller (1st) running
    our ERP software & SQL Server 2000 in Windows 2000.
    Because of the workload demand for this server, we
    purchased another more powerful server (2nd) that would
    replace the role of the first server as DC. The new
    server has Windows 2003 which should take the role as DC
    and file server.

    1. How can I migrate the Active Directory of 1st(Win2k
    server) server to 2nd(Win 2003 server) server?

    2. How can I demote the 1st(win2k) server to act as a
    member of the 2nd(win2003) server without affecting the
    users of ERP & SQL?

    Any help is highly appreciated. Thank you.

  2. Hi Cley,
    What you need to do generally is:
    1) Read through this chapter from the Deployment Kit (URL wraps):

    Upgrading Windows 2000 Domains to Windows Server 2003 Domains

    http://www.microsoft.com/resources/documentation/WindowsServ/2003/all/de
    ployguide/en-us/Default.asp?
    url=/resources/documentation/WindowsServ/2003/all/deployguide/en-
    us/dpgDSS_overview.asp


    2) You need to promote the Win2K3 server as an additional domain
    controller in the existing domain. This requires some preparation like
    running adprep /forestprep and /domainprep in the existing domain prior
    to the introduction of Win2K3. The information is outlined in the above
    chapter.

    3) After completing the promotion, you'll need to transfer all FSMO
    roles to the new server. Use these articles as guides:

    HOW TO: View and Transfer FSMO Roles in Windows Server 2003
    http://support.microsoft.com/?id=324801

    HOW TO: View and Transfer FSMO Roles in the Graphical User Interface
    http://support.microsoft.com/?id=255690

    4) Install (if not done already) DNS on the Win2K3. On the Win2K make
    the DNS zone AD-integrated and then add it to the Win2K3 DNS. Point the
    Win2K3 to itself for Primary DNS server.

    5) Make sure the environment works correctly and that both DCs have
    registered records in DNS and respond to clients. You can use tools like
    Dcdiag.exe and Nltest.exe which come with the Support Tools on the
    Win2K3 CD.

    6) Demote the Win2K to a member server by using Dcpromo.

    I would really recommend that you:
    - Test this migration in a lab
    - Make a complete backup of the Win2K server prior to migration

    If everything goes smoothly I don't expect you to have problems with the
    ERP software since it couldn't have used local accounts and the accounts
    will remain intact but on the new DC. However, *don't* increase the
    domain or forest functionality level at this point unless you are 200%
    sure it will not break any line of business app or the ERP system.

    Feel free to post again if you have any other concerns.
