Zimbra 4.5 upgrade

[3RiversTechAdmin]

Hey everyone,

I am upgrading 4.0.2_GA_362.DEBIAN3.1 running on Ubuntu 6.06 to 4.5. I was wondering if anyone has had any issues? I have custom changes in my config files, such as making the webmail https, etc. Will these configuration changes be preserved?

First, you should search bugzilla for issues.
Also, there have been some known issues with mysql and spamassassin.

As for the changes you made, if they were made through Zimbra's interface (Admin or CLI) they should be maintained.

I would recommend you wait for the 4.5.1 release which will out out shortly, it has fixes for the MySQL bug and a few others.

I think I will wait for 4.5.1, I may image my drives and try this upgrade on another machine.
