I'd like to upgrade my Oracle Glassfish Server 3.1 to 3.1.1 (linux platform). The server is in closed network hence not reaching internet. How can I upgrade to version 3.1.1? I was using ogs-3.1-unix.sh to install GF, now I have ogs-3.1.1-unix.sh which would overwrite my domain1... I guess. Should I just move the domain/node directories away and run the 3.1.1 the installer then move the domain/node back? Would this be working? Any help is appreciated.
