How to perform a dist-upgrade?
Warning: The dist-upgrade procedure is complex, hence you may want to consider migration instead as can be seen here: Plesk Migration and Transfer Guide
Warning: The dist-upgrade procedure can not be performed in a containerized environment. If this is not known, contact the server provider in order to know if the server or the environment is a container.
The dist-upgrade procedure is supported in Plesk as per the following versions:
| Supported for | Plesk version |
|---|---|
| Ubuntu 18 > Ubuntu 20 | Plesk Obsidian 18.0.33 and above |
| Ubuntu 16 > Ubuntu 18 | Plesk Obsidian 18.0.30 and above |
| Debian 9 > Debian 10 | Plesk Obsidian 18.0.30 and above |
| Ubuntu 14 > Ubuntu 16 | Plesk 17.8 |
| Debian 8 > Debian 9 | Plesk 17.8 |
If you have never performed dist-upgrade before, it is recommended to test it first as follows:
-
Install the previous version of OS on a test server or inside a virtual machine. Upgrade it using instructions provided in the documentation by the OS vendor:
-
Solve all potential problems and make sure that Plesk is working after the upgrade. Only after that run the upgrade on the production server.
If you want or need Plesk to assist on this task or to do it on your behalf, it can be requested to Plesk Professional Services team here: Plesk Prof…
