How to delete a domain from a Domain Controller, but keep the subdomains?

  • 772

If I have a domain : corporate.com

With 3 subdomains :

  • dev.corporate.com
  • voice.corporate.com
  • vpn.corporate.com

How can I delete the top domain, but keep the 3 child zones?

Specifically for Windows DNS, this would look something like this : enter image description here

I suspect there is no easy way to do this, which means I manually have to edit the entire zone file to end up with 3 separate zone files for the child zones. But I'm hoping I'm wrong. Any ideas?

migration domain-name-system active-directory

    It's not possible until you make 3 separate zones for 3 subdomains. Are you trying to move your main domain onto another server? If you want to do this there is no other option except to develop 3 separate zone.

  2. It is not possible to do this without some heavy modification of the data (programmatically modifying the zone data file to remove the parent zone, and then reloading the zone from the new file).

    Indeed it is far simpler to migrate things in the opposite order

    • Migrate subzones first (using zone transfer)
    • Then migrate the parent zone if needed
