• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Upgrade to Plesk 12 from Plesk 9.5.4

New Pleskian
I need to update a Plesk 9.5.4 server to Plesk 12. The installer tells me that I first need to upgrade to, at least, Plesk 10.4 before upgrading to Plesk 12. But, I can't find out how to upgrade from Plesk 9.5.4 to Plesk 10.4, only version the installer is showing is Plesk 12.
 
You have the choice to list all available options for the autoinstaller with the command:

/usr/local/psa/admin/bin/autoinstaller --help

You will then see, that the command - string "--select-release-id PLESK_10_4_4" will allow you to choose the latest stable version of Plesk 10.4.
The complete list for your current operating system will be displayed with the command - string "--show-all-releases"


A command line to upgrade to Plesk 10.4 would then be for example:

/usr/local/psa/admin/bin/autoinstaller --select-product-id plesk --select-release-id PLESK_10_4_4 --upgrade-installed-components

( even that I suggested now the full command line, please have a look at ALL AVAILABLE OPTIONS, like I first suggested. )
