There are always bugs between MySQL version

[Loortambel]

There are always bugs between MySQL version, so once we upgrade to the latest version with a bug, we are unable to install the previous version. For example, MariaDB 10.1.41 has a known bug and we want to install 10.1.39. The risk of downgrade is on us.

Any idea???

Unfortunately it's common for MySQL/MariaDB that downgrade is not fully supported, and it doesn't depend if you use CloudLinux OS or not.

The workaround is always the same - perform a full databases backup before the upgrade, do the upgrade and if something goes wrong - uninstall the latest version and install older from scratch, then restore the backup. There are a couple of good recommendations on how to improve the dump/restore speed, for example: https://stackoverflow.com/questions/...l-dump-restore
