A few pointers - sorry if some may be blindingly obvious.
Obtain a definite list of all devices with static IPs. All sorts of devices like printers, even switches with management IPs, etc can be hiding away on your network. These will obviously need to be manually changed over to the new range.
Ensure that any IP-based access control lists anywhere in your network are updated.
