I have an existing WHM/cPanel deployment that I'd like to phase out. Currently I have a primary domain with a vanity nameserver along with a few add-on domains that point to this vanity nameserver. My question is, is it possible to perform a seamless migration where none of the domains will require a nameserver update? The plan of attack so far: Copy the files and databases over Setup necessary virtual hosts Re-create all the necessary DNS records for each domain (using DO DNS panel) Change IP address for NS1. and NS2. for the primary domain I only have ns1. and ns2. currently– however Digital Ocean also has ns3. Will I need to add the ns3 nameserver to the other domains as well?
