Is it possible to replace MySQL with MariaDB and vice versa?
Yes, it is possible to replace MySQL with MariaDB. MariaDB is considered to be a drop-in replacement for the corresponding MySQL version (i.e MariaDB 10.2 and MySQL 5.7). The vice versa replacement, MariaDB to MySQL is also possible.
- Please review feature differences between MariaDB and MySQL to make sure the switch won't affect applications using database server. If application installation requirements mention that both MySQL/MariaDB are supported like WordPress for example, switch should not make any harm.
- The procedure should be performed by a system administrator. If you need help, Plesk Professional Services can perform this task for you.
- For steps to perform a switch please refer to our blog article MySQL Vs MariaDB – Can One Replace The Other?
NOTE: If it is required to have the different database server type for customers databases, the recommended solution is to use a Docker container to host separate MySQL or MariaDB instance in Plesk and add it as and external SQL database server using IP address 127.0.0.1 and the external Docker port.
