Upgrading from 4.0.2 to 4.5.5

[MikeStewart]

Hi,

We're just about to upgrade from 4.0.2 to 4.5.5

Are they any known problems or things we need to watch for ?

Running under Fedora Core 4.


TIA

Well, I'm running Zimbra on CentOS, and I've always done the upgrades incrementally (no version skips), but I've never had any issues with any of the upgrades. In fact, the Zimbra upgrade process is one of the easiest and best I've run across. Just from being around the forums for a while I don't recall seeing any posts about issues with Fedora, but you may just want to do a little searching around before you proceed. Of course, you absolutely should do a full backup of Zimbra prior to doing the upgrade just to be safe. You never know what you may run into.

Please make sure that you take a look at the Critical bug alert in the announcements thread.

Our current public build doesn't fix this, and you'll need to run that fix.

What do I need to backup in case of a disaster ? I've found /opt/zimbra are there other file/directories ?

Thanks

If your mail store or anything else is elsewhere (not in /opt/zimbra) then obviously you need to back that up.

But it sound's like you have everything there (in /opt/zimbra/).
-so do a tar, rsync, scp, cp, etc, etc on that folder. (or do it in the GUI)
-with your best effort to keep all the permissions; though there is a permissions reset script if you forget, it's still better to not have to use it

(also, backup instructions can be found in the wiki)

Many thanks mmorse,

Seems to be quite simple. And thanks for pointing me to the wiki, it's really useful.

If you get adventurous there are cold backup scripts available in the forums & on sourceforge (search the forums for the thread).
