To change an IP address (or addresses) of a Windows computer, either server or workstation, isn't a complex task, but possible consequences may often confuse people having forgotten those.
If the computer is running a DNS server, you should change all the records associating the name of the server with the old IP address.
If the computer is running a DHCP server, make sure you are using the correct range, and the new IP is excluded from dynamically lent addresses.
If processes/devices are using IP address to connect to the computer, perhaps it's worth to retain the old address when possible, to make the switch smoother.
If connection is done by domain name, you should take into account that, unless it's an intranet (private) address, DNS propagation may take several days to happen throughout the world (typical range is 48-72 hours).
All these notes should be well taken into account to prevent service disruption or any other disaster that can happen due to connectivity loss.
