I registered and created NS1.MYDOMAIN.COM at opensrs.org, some people use this NameServer to register their own domains at serveral registrars (dotregistrar, netsol, corenic etc).

The problem is i want to move to different server and I need to change IP address of NS1.MYDOMAIN.COM. How to do it?

is it enuff for me just to change my NS1 IP# at opensrs.org, then other registrars will follow to my new NameServer IP? or what?
Last months i tried to change my Nameserver IP, but some registrars are still pointing to old IP.

please help.
