In order to provide you with greater flexibility and more database options, we will be adding MariaDB 10.0 database support to cPanel & WHM version 11.48 in the first quarter of 2015.
MariaDB acts as a MySQL® replacement, and all interface and API function calls that refer to MySQL will work seamlessly with MariaDB, too.
Please note that if you upgrade to MariaDB 10.0, you cannot revert to MySQL. The system cannot safely perform downgrades, and it considers MariaDB to be an upgrade from MySQL.
Also, please note that some of the interfaces will still display MySQL after you install MariaDB. In future releases, we will update the user interface to explicitly reference MariaDB if you decide to upgrade to MariaDB.
