Plesk has three editions: Web Admin, Web Pro, and Web Host. Each license is available in one of two platform types:
- VPS, fits any virtualization platform: Virtuozzo (containers and VMs), VMware, Xen, Hyper-V, and so on.
- Dedicated, can be installed on either a VPS or a dedicated server.
Upgrades and downgrades between editions are available only for monthly lease licenses. The following upgrade paths are available:
- From Web Admin to Web Pro or Web Host
- From Web Pro to Web Host
Upgrading is also possible only within a license’s platform type: VPS licenses can be upgraded to VPS licenses, while dedicated licenses can be upgraded only to dedicated ones.
Plesk editions include the following extensions:
|Extension||Web Admin||Web Pro||Web Host|
|Security Core with Atomic Standard ModSecurity rules from Atomicorp||Yes||Yes||Yes|
* The paid extension is not available for an edition when it is already included in the edition.
If a lower edition license with a paid extension is upgraded to a higher edition where the extension is included, the extension becomes free. If a license with a free extension is downgraded back to a lower edition where the extension is not included, the extension becomes paid again.
Previously, SUS was included in domain features. For Plesk Onyx and Obsidian, the domain limit is a part of the license type; therefore SUS for purchased licenses should be available as a separate feature: 1 year SUS for Plesk (Purchased). SUS is mandatory during the initial purchase.
Plesk Onyx and Obsidian work with Plesk 10.x/11.x/12.x or later lease licenses.
Purchased licenses for earlier versions of Plesk can be upgraded to Plesk Onyx and later if they have the SUS feature. Learn more about upgrading licenses.
