Adding existing server to DNS Cluster

Hello, I read following documents but still have questions.

• Guide to DNS Cluster Configurations - cPanel Knowledge Base - cPanel Documentation

- I have a webserver that actively working with cPanel/WHM. Let's call this MainServer. - This mainserver using this nameservers: ns1.mainserveradress.com ns2.mainserveradress.com I have second server. I would like to create new accounts on this second server. But I want them to use mainserver's nameserver addresses. So I bought VPS, I installed DNSONLY cPanel. I enabled dns clustering on this VPS. I did same with my mainserver. How can I make this happen to work? Should I install DNSONLY server with nameserver as hostname? Should ns1.mainserveradress.com need to be hostname for DNSONLY server1?

  Hello, You'd simply ensure the name server IP addresses associated with NS1/NS2.mainserveraddress.com at the domain registrar were associated with the IP address(es) of the DNS-Only server. We provide a guide on how to setup the name server IP addresses at the domain registrar here: How to Set Up Nameservers in a cPanel Environment - cPanel Knowledge Base - cPanel Documentation Thank you.

  Hello, Yes, those steps are correct, except for:

  I'll enable DNS CLUSTER for all servers and add them all to eachother.

  
  You actually only need to configure clustering on the two web servers using the "WHM >> DNS Cluster" option. See: Thank you.

  You will need to migrate your existing nameservers. This is more complicated, with a greater likelyhood of service disruption, than either: ->Set existing nameservers as default NS in new hosting server ->Create new nameservers (with new hostnames) and updating the nameservers of existing domains With only two nameservers (based on example), you are guaranteed to expose your hosting accounts to some period of downtime

  c1.mainserver.com to ns1.mainserver.com is required for that to work? Or if I just change nameserver IP's of that is enough?

  
  Hello, Changing the name server IP addresses is sufficient as long as those IP addresses are already added to the DNS-ONLY server. Thank you.
