I've recently had to change the IP of one of my nameservers - ns2.xxxxx.com

It's been several days, and it still points to the old one. Can someone give me a list of all the steps I need to take to correctly change the IP? I'm using a CPanel server and I got a feeling I'm missing some important step.

If it helps, ns2 and ns1 used to point to same machine, now ns2 should point to different one. I've setup DNS clustering so NS1 and NS2 share DNS info, with ns1 being primary server.

Thanks.

but give it time, when i set my name servers up they took a week!

It still hasn't switched over. I periodically got the new IP, but now it's the old IP for me and anyone else that pings it :/

Some list of instructions for changing a nameserver IP correctly would be really helpful.
