It really easy!. 1) Make your EJB clusterized -- Add Annotation @Clustered on any EJB 2) copy cluster-service.xml from all to default 3) copy ejb3-clustered-sfsbcache-service.xml from all to default (if you have SFSB) 4) and finally modify you jndi.properties change port from 1099 to 1100. (on clients app) I'have make this 1000 times for many customers, tell me if it work for you?
