Patch upgrade
For minor version upgrade or patch upgrades we can use:
- Take backup of VM through snapshot etc. if possible. Other option is to take backup of entire /opt/zimbra folder.
- Take copy of /opt/zimbra/conf at another location for quick reference after upgrade
- Stop Zimbra as zimbra user
- zmcontrol stop
- Update packages as root user
- yum -y update
- Compare old copy of /opt/zimbra/conf with new copy for any manual changes that might have got overwritten during upgrade.
- Start zimbra again
- zmcontrol start
Major upgrade
For major version upgrade:
- Download the updated version of zimbra in .tgz (Zip) format
- We must keep both old and new zimbra setups with us for future recovery / restore operations
- Extract the files of updated version
- Take copy of /opt/zimbra/conf at another location for quick reference after upgrade
- Go through installation of zimbra using "./install.sh" with required platform override, if required
- The installer will automatically detect existing version and go through the update process.
- Compare old copy of /opt/zimbra/conf with new copy for any manual changes that might have got overwritten during upgrade.
Caveats from update
Following things have been noticed to get affected due to upgrade, which must be fixed promptly:
- Spamassasin configuration and scores might get overwritten
- CentOS 8.x Zimbra Configure spamassasin email score based on client RBL
- CBpolicyd security configuration via http might get overwritten
- CentOS 7.x Configure cbpolicyd for Zimbra 8.7
