Yes, possible.
- First server:
- Stop Gluu-Server container.
- Tarball it
- Second server:
- Install same Gluu Server version's rpm. Just rpm or `yum install`.
- You don't need to run setup.py this time.
- Grab tarball from first server
- Delete 2nd server's created 'gluu-server-3.1.6' from `/opt`
- Untar previous Gluu Server tarball in 2nd server's `/opt`
- Start it.
