This article applies to Plesk 9.3 for Linux running on CentOS Linux 5.5 64 bit including the ART PHP/MySQL packages.|
Please note: before starting the upgrade procedure please contact IDAQ Support and let us know. Parallels changed their licensing model a while back and licenses we originally purchased from them for Plesk 7.x, 8.x and 9.x may not be valid for upgrade to Plesk 9.3/9.5.2. Parallels changed their licensing model and we now have to lease licenses from them.
- Make a full system backup and ensure backups work
- Upgrade Plesk 9.3 to the latest 9.3 updated version via control panel (if not already)
- Plesk control panel (System->Updates) may still be saying updates available for 9.3, so, log in via command line and run:
/usr/local/psa/admin/bin/autoinstaller --upgrade-installed-components --select-release-current
This should upgrade the Plesk 9.3 installation to the latest Plesk 9.3 packages.
- Then, select Plesk 9.5.2 from the System->Updates menu and select most packages that have available updates except for application pack.
- Before starting the upgrade: the upgrade process can take between 20-50 minutes depending on the number of sites and features enabled. At one stage the Plesk upgrade procedure shuts down the webserver and runs a quota check. Checking quota on a system with many sites and large hard drives can take over 30 minutes alone.
- Start the upgrade and if you want, on the command line you can follow progress by running: tail -f /tmp/autoinstaller3.log
- Now, hopefully Plesk 9.5.2 has installed
BugsThis upgrade was relatively pain free and resolved a bug in horde webmail.
You may need to manually start spam assassin as it appears that it was not restarted after the upgrade process. From command line run: service psa-spamassasin start
