I had 2 DNS servers. One was just a secondary on a member server. I built a new domain controller and now have DNS running on that integrated with my old domain controller. My secondary DNS server is still pointing to my old domain controller under the zones properties on the Start of Authority (SOA) tab. Everything here is greyed out but I want to update this SOA so that the new DNS server is listed under Primary server. I was able to replace the old domain controller IP on the General tab under Master Servers with the IP of the new DC.
How do I make this change for the secondary DNS?
