I have a NWSB server hosting domain eMail (GroupWise). The client is
moving from one carrier to another, necessitating an IP address change.

The internal LAN segment(s) will not change, the WAN address, gateway
and DNS are all changing.

What's the easiest way to change the IP addressing, given that all else
will remain the same; domains, etc.

Thanks for the help...
