Sure, take care of assymetric routing which breaks traffic, but if you have the free external public addresses in place it should be as simple as changing the lan hosts gateway to the new firewall. This can frequently go very wrong though, do take care of assymetric routing or IP conflicts. Rebuild the entire network with VMs in ESX, vswitches and all, then bring up vms on various vswitches for testing, ping, tcp, udp etc. I rebuilt my entire production work network in ESX, carp et all so I can perform upgrade testing.
