I am currently using Debian 5 and Plesk 10.0.1, and would like to upgrade to Debian 6 and Plesk 10.2. After reading posts in this forum, I am a bit concerned with upgrading the server. I would like to update to Debian 6 because of PHP 5.3 and the new features in Debian 6 and Plesk 10.2. I couldn't find any information about how to upgrade Debian prior Plesk, and I was hoping someone could give me some hints about how to upgrade without any problems. Here is my upgradeplan: 1. Perform full serverbackup (using rsync) 2. Upgrade Debian 5 -> Debian 6 3. Upgrade from Plesk 10.0.1 -> Plesk 10.2 (using autoinstaller in terminal) When upgrading to Debian 6, new versions of mySQL and PHP will be upgraded. My concern is Plesk 10.0.1, because it will break the compability - but will this be fixed when running a upgrade to Plesk 10.2?
