[RCU] Upgrade Process

I have a working installation of RC v0.2.2 on my Linux server. I would love to upgrade to the latest v0.3-stable however I would like to know how I can perform the upgrade without and loss of data. If I do a fresh install, I would think that the installer would wipe all my MySQL database tables and data...which would be bad. Can someone please explain to me the process of upgrading from my current version to the latest version on my server? I searched the Wiki and only found "fresh install" instructions.

Thanks for any help! _______________________________________________ List info: http://lists.roundcube.net/users/
