I would leave 4.2.2 as is and change the ports on 5.0. To do that, look at the server/xxx/conf/bootstrap/bindings.xml file. All of the ports are configured from this file in 5.0. In fact, you could start 5.0 like this: run -Djboss.service.binding.set=Ports01Bindings and it will run with port numbers increased by 100 (example: using port 8180 instead of 8080) If you want to change the ports on 4.2.x, see the file docs/examples/binding-manager/sample-bindings.xml, which provides a similar mechanism.
