Here is the doc:
# How to change container name after upgrade
## From 3.1.3 to 3.1.6
In Gluu Server version < 4.0, container names are unchanged after version upgrade. Say, if you upgraded your previously installed Gluu Server v3.1.3 to v3.1.6, your container name will be 'gluu-server-3.1.3' though you are running 3.1.6 inside.
Here in this doc we are showing how you can change your container name in CentOS7x.
- `/sbin/gluu-serverd-3.1.3 stop`
- `/sbin/gluu-serverd-3.1.3 disable`
- `mv /sbin/gluu-serverd-3.1.3 /sbin/gluu-serverd-3.1.6`
- Change 'GLUU_VERSION' from 3.1.3 to 3.1.6 by `vim -N /sbin/gluu-serverd-3.1.6`
- `mv /opt/gluu-server-3.1.3 /opt/gluu-server-3.1.6`
- `cd /var/lib/container/ && ln -s /opt/gluu-server-3.1.6 gluu_server_3.1.6`
- `rm gluu_server_3.1.3`
- `mv /usr/lib/systemd/system/systemd-nspawn\@gluu_server_3.1.3.service /usr/lib/systemd/system/systemd-nspawn\@gluu_server_3.1.6.service`
- `/sbin/gluu-serverd-3.1.6 enable`
- `/sbin/gluu-serverd-3.1.6 start`
## From 3.1.1 to 4.0
- `/sbin/gluu-serverd-3.1.1 stop`
- `/sbin/gluu-serverd-3.1.1 disable`
- `mv /sbin/gluu-serverd-3.1.1 /sbin/gluu-serverd`
- `Change 'GLUU_VERSION' from 3.1.3 to 4.0 by `vim -N /sbin/gluu-serverd`
- `mv /opt/gluu-server-3.1.1 /opt/gluu-server`
- `cd /var/lib/container/ && ln -s /opt/gluu-server gluu_server_4.0`
- `rm gluu_server`
- `mv /usr/lib/systemd/system/systemd-nspawn\@gluu_server.service /usr/lib/systemd/system/systemd-nspawn\@gluu_server_4.0.service`
- `/sbin/gluu-serverd enable`
- `/sbin/gluu-serverd start`
