It seems you want to change the IP address of the UC applications.
you can refer the doc below the change the ip address of the UC applications. however make sure you have a proper plan of doing this as this might lead to db issues and most common one you might end up with is an "Database communication error" on gui page of cucm and might not be able to login to ccm page.

although its just two commands to change the IP address but if we do it without any plan/consideration would affect all other dependencies configured in application such as Gateways, trunks CTI ports etc etc. So, make a plan first and refer the document prior doing any changes.
