Unfortunately we're having to move one of our servers to a new subnet - a completely new set of IP addresses. Every IP, including our main IP, will change. This is the second server in a multi-server setup.
If anyone's done this before, can you confirm what needs to be done for this to work? Obviously, I understand how to add new IP addresses and make new assignments, but I don't know how to change the main server IP - and any possible problems this may cause.
Also, I'm worried that if I delete the IP from the multi-server setup and add the new one (on the first server) it will screw up my DNS. Any advice would be warmly received! Thanks.
