Downgrade MariaDB

Hello,

I recently upgraded MariaDB 10.0.21 to 10.1.8. Our program that interacts with it is tossing errors and we found out it's not supported by the program. We were directed from the application dev team to install 10.0.21 back. I cannot find any documentation on how to properly downgrade the DB and move the data to an older version. Any specific process to follow?

To downgrade you will need to export (do a dump) as there will be a bunch of table changes in the mysql database and other pieces of the core tables.

You might want to try and work through the issues and tweak settings to adjust. very few apps ever truly have issues unless the software uses a deprecated feature.
