Server 2008 AD/DHCP/DNS Migration Assistance


  • Hello,

    I have a scenario as follows:

    - Currently Server 2008 R2 x64

    - Server has the roles of DHCP, DNS, and AD

    - Currently there is no backup DC, but current DC is functional. However, there is corruption with the install, entirely seems to be .NET related. SFC and the like can't repair it, and manual repair hasn't led to anything successful.

    - Because of the corruption an in-place upgrade to 2012 fails, it installs but get a black screen. From what I researched this can happen if an admin uninstalls .NET, considering the .NET is corrupted, this makes sense.

    What I'd like to do is:

    - Create a new server, install 2012 on it.

    - Add server as a backup DC.
    - Setup DNS on the server.
    - Demote the old DC and remove it.
    - Setup DHCP and migrate over the current DHCP database.

    - Afterwards, setup another 2012 server as a backup DC and DNS.

    Due to having some security devices and whatnot set to a static IP and referencing the DNS server statically as well, I'd like to, after the above, change the new servers IP to the old servers IP.

    Is there any potential issues seen with this arrangement?

    Edit: Meant to put this question in Server 2012 Setup Help...
