changing resellers DNS to his own ??

Hi guys!

When we add an reseller account it auto gets the default nameservers.
What to do when the reseller would like to use his own nameservers on the
servern for his own domain installed with the default nameservers ?

Can I just delete the default ns record in DNS settings and add his own
ns their instead.

He hsa nameservers and IP's setup on the server.

Thanks!

 

Thanks!!

Do you change the SOA record also ?
In there is also ns1.defaultnameserver.com and e-mail to server
