I know there must be already lots of posts and maybe wiki instructions on how to upgrade Zimbra, but to sumarise again, please, can somebody confirm upgrade steps:
- first BACKUP at least /opt/zimbra
- then my first dilema:
o to use web Admin interface
o or to use CLI terminal
- after getting newest version (in my case 6.0.3 upgraded to 6.0.6), just run ./install.sh and relax
1.) Will all my settings be preserved?
2.) Must I manually stop Zimbra MTA before I begin?
3.) Will SSL certificate remain in place and be used in upgraded version?
4.) Any post-upgrade tasks?
5.) Any other precautions?
6.) If upgrade fails or gets broken, then I only restore /opt/zimbra from backup and everything is back as it was?
It's my only Zimbra install and it is production, so better to be safe then sorry.
