I've been told that a customer is about to change the ip address of their two zenworks primary servers.

we have the following configuration:
2 primary servers.
internal db on one of the primary servers
primary servers running sles 10 sp2
internal certificates
dns names will remain the same - only ip addresses changing.
zcm 10.1.3 installed
14 sat servers.
running windows xp sp3

are there any issues that we should expect to see if the ipaddresses are changed?
and are there any config files that need to be tweeked?
