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|
