How to migrate a secondary DNS server from 2003 to 2012 R2

Hello,

Yesterday i was migrating a Public DNS Service from MS Windows 2003 Server to MS Windows 2012 R2. Obviously these zones dns were not integrated in ADDS.

The strategy is easy:

In 2003 Server:

  • Export from regedit the subkeys [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DNS Server\Zones]
  • Copy c:\windows\system32\dns
  • Shutdown server.

In 2012 R2 Server:

  • Configure same ip, mask, gateway and dns servers on the ethernet than 2003 Server.
  • Stop DNS Service.
  • Import the .reg file.
  • Paste the *.dns files inside folder dns.
  • Start DNS Service.
  • Go to Properties of the DNS Server ad configure exactly as 2003 Server.
  • Check all DNS Zones are ok.
  • Check if replication from Master are working fine.

It´s all!
