We have been evaluating Zimbra and it has been chosen to take the place of our current email and calendering programs. We are running Network Trial version 4.5.5 for our testing and I see that 4.5.7 has been released. We would like to see how an upgrade goes. I would also like to install the beta version 5.0 to see some of it's new features. I am wondering if there is any documentation on performing an upgrade. Does it keep your server settings and do you have to install the updates in order? Meaning, can I skip a version and go directly to the version I want. By the way, I am so excited about becoming a Zimbra Administrator for our company.
The upgrade is extremely simple, just run './install.sh'.
Now, obviously, you'll want to run a backup before you do that but otherwise there's nothing special to do. You also don't need to run any intermediate releases, you can just install the current version. That said, you should always check the release notes before doing an upgrade just in case there are any special instructions or 'gotchas'.
The beta 5 version for Network Edition hasn't been released yet, it's due soon.
