Question : Change IP address of Single Network Adapter ISA 2006

We are using ISA 2006 on a Windows 2003 server but only use it as a Single Network Adapter setup for Web publishing. We have been informed by our Local Authority that we need to change our internal IP range to a new range. Are there any implications on the ISA 2006 server that I need to be aware of or are there any procedures that I need to carry out after the change.
