Replacing old win2k server with new win2k server

Discussion in 'Active Directory' started by Øystein Sund, Dec 5, 2005.

  1. We have an old win2k server with lack of hardware space and performance
    which we are going to replace with a new server with the same os. The old
    server is running active directory.
    How is the best way to do this without having to install a new domain
    controller?

    The way I see it, it must be to install the new server and choosing
    "Additional domain controller for an existing domain" when installing the
    active directory services. Will the ad user database automatically be
    updated? After doing this, is it possible to just pull the plug on the old
    server and the new server will just become the primary server?

    I will be truly greatful for any advice on this issue!

    Regards
    Oeystein

    Your description is correct.

    1. Install a new, additonal DC
    2. The AD database will sync over to this new DC as part of the promo phase
    3. Transfer any FSMO roles from the old to new DC
    4. Transfer any apps from old to new
    5. Update any scripts or apps that point explicitly to the old DC and change
    to point to new
    6. Demote old DC
    7. Power off old DC

  4. I would say there are two things missing - DNS and GC. In a single DC
    environment, this will be a killer. Take a look at this, it discusses this
    issue:

    Note. That doesn't cover EFS. I know it should, but at present it doesn't.
    If you are using EFS, that is an additional step covered in a KB.

    Thanks for the clarification, Paul.

    I'd hoped I had covered this off in my catch all steps 'move apps and
    dependencies'.

  6. You did. However, I thought I'd clarify in case some unlucky junior admin
    is Googling for help.
