Moveing DNS from Win 2000 to Win 2003

Posted on 2006-04-07

I am going to be replacing my Win 2000 server shortly. It is configured as a domain controller and we run DNS server on this as well.

I intend to promote the new Win 2003 server to domain controller, demote the Win 2000 server.

The only question I have is. how do I copy the DNS data across. There are some manual entries in the exisiting DNS server and I would like to copy the data to eliminate the manual reentry.

    Before you promote the new machine, make sure all your DNS zones are AD integrated.
    Promote the new machine, install DNS, do NOT create any zones manually. Shortly after you install DNS, the AD integrated zones from the W2k machine will be replicated to the new machine. Change the DNS settings of the new machine to point to itself, depromote the old machine (which will remove the AD integrated zones from the W2k DNS).

    Ok - but one thing that I did not say was that there is another domain!
    say machine Server for abc domain Server for xyz domain is the machine which will be the new abc domain controller.

    The xyz domain DNS records are held on the DNS server on

    Does your advice change as I would assume that the trasnfer would only take place on the abc domian?

    DNS and AD are completely independent services; so as long as you make sure the DNS zone(s) for your xyz domain are AD integrated, it will be replicated to the new machines as well.
    Just don't forget to change the DNS server entry on the xyz DC to point to the new one, before you demote the old abc DC ...
