I'm hosting a few clients' websites on a Media Temple VPS, but I'm thinking of moving to another provider. When I originally set up their sites I had each client point their domain names to MT's nameservers. So now, if I switch, I'll have to contact them and get them to point their domains somewhere else.
My question is whether I could have avoided this by setting up a CNAME record for one of my domains (like ns1.mydomain.com and ns2.mydomain.com) and pointed those to MT's name servers. So that if I decided to switch I could just make a change on my end and not have to bother them? Will something like that work? Or is there another way?
