Plesk 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.
The currently supported Plesk versions are:
- Plesk Onyx
- Plesk 12.5
- Plesk 12
- Plesk 11
- 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.
Version Lifecycle Dates
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:
|Product||Released||Extended Support||End of Life|
|Plesk Onyx||October 11, 2016||October 11, 2020||April 20, 2021|
|Plesk 12||June 16, 2014||June 16, 2018||January 1, 2019|
|Plesk 11||June 13, 2012||June 13, 2016||December 13, 2016|
|Plesk 10||November 3, 2010||January 31, 2015||May 3, 2015|
|Plesk 9||December 9, 2008||December 9, 2012||June 9, 2013|
|Plesk 8||September 20, 2006||March 1, 2012||September 1, 2012|
|Small Business Panel*||November 3, 2009||August 1, 2011||July 1, 2012|
|Plesk 7 and earlier||February 10, 2004||n/a||January 1, 2012|

* The upgrade path for Small Business Panel customers involves a migration to Plesk 10, where these products were merged. See the relevant documentation for further details.
Operating system vendors have established formal end-of-life policies around the operating systems they develop and maintain. Using a supported operating system is critical to maintaining a stable server environment. As a result, Plesk maintains a lifecycle policy related to operating systems as well.
OS Versions Lifecycle:
- For supported versions Plesk will provide software patches and accept technical support requests for that Plesk instance – provided the environment in which it is running utilizes an operating system that is within its production lifecycle.
- Support for a particular Plesk instance will end at the earliest of either the standard product lifecycle or the vendor termination date of the operating system on which that instance is running. A newer operating system version may be used in order to continue receiving support through the rest of the release lifecycle.
- As new releases become available, Plesk may consider which operating systems and versions thereof to include in that release or remove from that release. This will not affect the support status of existing releases; they will continue to follow the tables below.
- Typically, support for new operating system versions will only be added to the most recently released Plesk version. For example, a new version of CentOS would be added only to the latest Plesk release, but not to any earlier versions.
To assist with monitoring operating system production lifecycles, Odin offers the below tables describing the dates by which a particular operating system ended its production life cycle and, synonymously, when Odin will no longer provide software patches or accept technical support requests for Plesk instances running on these operating systems. Odin recommends monitoring this list and ensuring that customers’ operating system environments are kept up-to-date.

**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.
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 instructions for migration, please check out our migration process guide If you prefer to migrate on your own but need consulting assistance Plesk offers free migration assistance from older versions.
If you prefer to let Plesk professionals handle the migration (or in-place upgrade) job and verification checks for you Plesk provides paid migration service.
