Name servers not showing correct IP through WHOIS

[Mark Hutchings]

When I run a whois for a domain that a customer has purchased through 
us, it is showing the IP for nameservers that has been changed a long 
time ago.  The domain (that is running the name servers) is through 
GoDaddy (big mistake) and the IP information was changed through there 
several months ago.  When I run a whois on the name server, it shows the 
right IP address.  But when I run a whois on any domain thats been 
registered through us before the IP addresses were changed, those 
domains show the old IP address on the name servers.  How can I get all 
these domains to see the correct IP address of the name servers? 

On a side note, when we transfer the domain to OpenSRS, will all the 
name server information transfer with it, of will I have to readd the 
name servers through OpenSRS?
