You are correct, you will need to manually edit every rule. I assume you
are talking about changing your whole IP schema... every PC, Servers,

To make this simpler in the future use the "Aliases". These are
shortcuts you can use when defining firewall and NAT rules (any blue
field can be filled with an Alias). Aliases can be Hosts or Networks
(i.e. subnets). If you need to change the IP of a host, you just have to
edit the appropriate Alias. Go to one screen change all the Aliases, you
are done (you don't have to touch the rules...)
