I have a reseler account, now I got a dedicatd server. I want to move all my clients, around 230.. to my new server without having them to change DNS.
I sow many webhosting companies having many servers around the world but using the same nameservers for all of them. like ns1.domain.com and ns2.domain.com for all servers.
I know one way is to change the IP from registerar, but my registerar doesn't allow me to do that. the message is: there are still domains resolving on that nameserver, it cannot be changed ot removed.
Can anybody please tell me how can I have 2 nameservers and use them for all my servers step by step?
