• 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 from 11.5 to 12

Hello,
we have bought Plesk 11.5 3 months ago.

Is it possible to upgrade to 12?
How do I have to proceed for the upgrade?

Thanks.

1. Existing Monthly Lease license is supported in Plesk 12.
2. Existing Purchased license should have active SUS, then the license version will be upgraded automatically during Plesk upgrade to v12.
3. If you want new Edition-based Plesk 12 license, you need to terminated the old one and buy new (there is no conversion from old licenses to new Edition-based licenses).
