Hello,
What’s the safest way to rename name servers. I have already 5 domains using ns1.old.com ns2.old.com and the domain name old.com is as child-ns.
I want to let expire old.com domain name and want to use new.com. So how to replace these 5 domains to use ns1.new.com and ns2.new.com
Do I need to edit them manualy in dns zones of this 5 domain names?
Thanks!
