For cPanel & WHM version 70
(WHM >> Home >> Software >> MySQL/MariaDB Upgrade)
This interface allows you to manage MySQL® or MariaDB® version upgrades (for example, when you upgrade from MySQL 5.5 to 5.6). After you select your MySQL or MariaDB version, WHM automatically keeps your database engine up-to-date. This means, for example, that whenever the vendor releases a new patch for your version of MySQL or MariaDB, WHM automatically applies the patch to your installation.
- We strongly recommend that you back up your database before you upgrade your database or change to MariaDB.
- This feature does not support downgrades of database engine versions. We strongly recommend that you do not attempt to downgrade MySQL or MariaDB.
- The system considers MariaDB to be an upgrade from MySQL. If you change the database engine to MariaDB, you cannot change back to MySQL.
- If CloudLinux's™ MySQL Governor exists on your server, MySQL upgrades will not work via the MySQL Upgrade interface. If you wish to remove MySQL Governor, read CloudLinux's MySQL Governor documentation and research how this affects you.
- We do not support the use of MySQL's
sha256_passwordplugin for MySQL 5.7 or MariaDB 10.2.
If your server uses a version of MySQL that is older than MySQL version 5.5, you must upgrade to MySQL version 5.5 before you can upgrade to MySQL version 5.6 or later.
The following versions of MySQL are available:
- MySQL 5.5
- MySQL 5.6
- MySQL 5.7
The following versions of MariaDB are available:
- MariaDB 10.0
- MariaDB 10.1
- MariaDB 10.2
