How to upgrade MySQL 5.5 to 5.6/5.7 or MariaDB 5.5 to 10.X on Linux?
Automatic Upgrade Tool via UI (Beta)
In the latest Plesk Obsidian 18.0.58 we have released our new tool to upgrade MariaDB to a supported LTS branch from Plesk UI.
Note: this tool is not available on CloudLinux.
Our tool checks configuration, performs DB backup, configures MariaDB package repositories, performs the upgrade, and runs necessary post-upgrade actions.
