Plesk Version Lifecycle Policy

Plesk is committed to providing high-quality, cost-effective solutions to our customers. Rapidly changing technologies influence the level, timing and character of demand for particular product versions and components. All of this drives the need to introduce new products and services as well as to end support for older software versions.

To assist our customers in this regard, we provide a clear lifecycle and end-of-life (EOL) policy to assist in planning decisions around using and upgrading both Plesk and the environment in which it is running.

Plesk Lifecycle Policy

  • A major version is defined as any change in the first digit(s) of the Plesk version number. For example, Plesk 12 and Plesk 11 are different major versions whereas Plesk 12.0 and 12.5 are not. From Plesk Onyx on, we will define new versions by a change in the version name as opposed to the version number.
  • A preview version is defined as any Plesk version, which is only available through the non-default “testing” release tier in the Plesk Installer.
  • Plesk will always provide software patches and accept technical support requests for the latest Plesk major version and its immediately preceding version.
  • Plesk does not accept technical support requests for preview versions of Plesk. To report bugs and ask technical questions, go to the Plesk Community Forum. To submit feature requests, go to our Plesk UserVoice.
  • Each major version will be fully supported for at least a period of four (4) years after release.
    • Extended Support: After this 4 year period, the product will no longer be available for new purchases and will continue to receive patches only for critical issues. This will last for a period of six (6) months.
    • End-of-Life: Once the Extended Support period is over, the product will stop receiving further development, and technical support requests will no longer be accepted.
  • In order to ensure stable operation, it is required to be on the latest update/patch within a major released version of Plesk. Preview versions must not be used in production environments.
  • Support for a particular instance is also dependent on using a currently supported operating system. This policy is described in the relevant section below.
  • Even for unsupported instances, Plesk will continue to accept technical support requests that are related to updating to a supported version or environment. Exceptions are updates from and to preview versions, since the stability of such upgrades is not guaranteed.

Plesk version lifecycle

Recommended versions*

* We recommend using the latest supported version of an operating system when deploying a new server. This is because a server with such OS has the longest potential lifetime before its OS Vendor Termination Date.

Unsupported OSes

Plesk does not accept support requests and will not issue software patches for servers with OSes, that are not listed in the table above or if their Vendor Termination Date is past due.

Migration assistance

If your Plesk version is approaching its End of Life phase or operating system is approaching its Vendor Termination Date, we recommend migrating your Plesk to the latest Plesk version and a newer supported operating system.

If you need migration instructions, advice, or if you would prefer to let Plesk professionals handle the migration for you, visit our Professional Services page.
