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 table below describes 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|

* 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.
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.
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.
