What DNS changes to make when moving hosts?
I have example.com as a reseller account hosted on a shared server. I have ns1.example.com and ns2.example.com on that server and client domains use these nameservers.I want to move to a VPS for more control and so I have acquired vps.example.com. This also has vps_ns1.example.com and vps_ns2.example.com with it.
Can I move everything to the VPS? Assuming that I move the files over, if I simply changed the DNS of example.com to point to nameservers vps_ns1(and 2).example.com, what would happen?
Have I made it over complicated for me to understand, and it's actually a lot easier than I think? Or have I shot myself in the foot by using vps.example.com as the name for the VPS?
I am using cPanel/WHM for both servers.
