Moving a DNS Only Server

I have 2 DNS Only cPanel servers (ns1 & ns2), running in a cluster for a single main cPanel server. I have dozens of domains whose nameservers are set to ns1 and ns2. I'd like to move ns1 from Rackspace to Linode and am looking for advice on the best way to do this, avoiding any downtime for my domains. i.e. can I just delete the ns1 server on Rackspace, and create a new one on Linode called ns1 and setup the A record? Or is there a better way? Thanks

  Hello :) You could setup the new DNS-Only server, add it to the cluster, sync the zones to it, update the "A" record for the name server to the new IP address, and then set the new IP address at the registrar for that name server. You can then disable the server that you are replacing. Thank you.

  Thanks Michael. But if my cluster already has the existing ns1.mydomain.com in it, will it really let me add a 2nd ns1.mydomain.com? As it seems to ask for the hostname when adding a server to the cluster. Should I just remove the old ns1 from the cluster, then setup and add the new one? James

  You can enter the IP address of the server instead of the hostname if you prefer, or yes, you could delete the existing name server before adding the new one. Thank you.
