I'm hosting a lot of domains which nameservers are set to ns1.domain1.com and ns2.domain1.com. I have rented a new server which for I have set up ns1.domain2.com and ns2.domain2.com.
Is it possible to forward ns1.domain1.com and ns2.domain1.com to ns1.domain2.com and ns2.domain2.com? Or is it required to change nameservers for all the domains via registrars?
Thanks for your help in advance.
