Moving everything to a new server: nameservers

I am in the process of moving a large number of sites and POPs from a (hacked, RedHat 6.1) server to a new one (RaQ4).

My colo has left the primary nameserver pointing at the old box but set the secondary to the new one. So I have:

ns.mydomain.net = IP of old box
ns2.mydomain.net = IP of new RaQ4

All the domains I am moving are pointing to these nameservers.

Can anyone suggest, please, how I can stop the domains resolving to the primary IP so they resolve to the secondary instead, so I can test them on the new one, short of turning the old box off? (I won't be able to turn it back on, it's miles away)

Also, my other RaQ4 uses "dns0 and dns1" instead of "ns and ns2". Where does this difference come from and is it important?

TIA for any help

Eddie
