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 versions

The currently supported Plesk versions are:

  • Plesk Onyx
  • Plesk 12.5
  • Plesk 12

Lifecycle Policy:

  • A major version is defined as any change in the first digit(s) of the 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 version number.
  • Plesk will always provide software patches and accept technical support requests for the latest Plesk major version and its immediately preceding version.
  • 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 cease to receive 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 version.
  • 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.

Plesk version lifecycle

The tables below describe when specific versions of Plesk will enter the Extended Support phase and when patches / support will no longer be available for them. If affected by one of the below dates, customers are encouraged to upgrade to a supported Plesk version:

**Plesk will no longer provide software patches for Plesk instances running on Windows Server 2008 R2, but will accept technical support requests for Plesk installed into Parallels Virtuozzo Containers running on this OS – till September 1st, 2013. We strongly recommend you to transfer your Plesk installation to any other supported operating system before this date. Refer to the Upgrade and Migration Guide for more details.

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.
