Can confirm MariaDB 10.2 is the minimum required version for Mautic 3, as it’s basically the same as MySQL 5.7. Versions older than 10.2 are not compatible. For more details, see this reply:

> Thanks for reporting back. We have taken the following steps to improve MariaDB support: [Add MariaDB to our CI testing pipeline](https://github.com/mautic/mautic/pull/8930)[Check for MariaDB 10.2+ (instead of 10.1+) in the Mautic 3 upgrade script](https://github.com/mautic/mautic/issues/8931)[Check if you’re running a supported database version in the clean installation process](https://forum.mautic.org/t/include-database-version-test-in-installer/14872) I will go ahead and close this topic now. If you came across any other issues, please feel free to let us know in a new topic slight_smile
