You'll need to change the IP address and possibily reset database replication. Take a DRS backup first and follow the IP change procedure to the letter.

Assuming your CallManager Group has the subscriber as the primary node and SIP/H.323 gateway dial-peers are pointed to the subscriber first, phones and gateways will continue to function. The database will be read-only so you won't be able to make changes.
