All you need to change is the IP address of the multilink interface. Also note that when you do this your multilink interface which is your NAT outside interface will drop all connections for a moment, until you configure the new IP address. Are you using PAT or do you use a range of IP address in a pool from the existing subnet allocated to you ? If yes, then you will also need to reconfigure the pool used for NAT to the new IP block.
To change Ip address of interface go to global config mode (Router(config)#) and execute following commands..
int multilink 1
ip add

That's easy enough, thanks for your help

Dont forget to reconfigure NAT pool if using NAT instead of PAT>...
