I've added 2 new name servers to my dedicated server so now i have this:

ns1.domain1.com
ns2.domain1.com
&
ns1.domain2.com
ns2.domain2.com

I noticed in the WHM > Edit Settings > there is a primary and secondary name server that states these are used when setting up new accounts. I can change these without worry can't I? Specifically to the new nameservers above and the old ones would still work eh?
