mariadb-upgrade & mysql_upgrade for MariaDB Enterprise Server


The mariadb-upgrade utility examines the data directory for incompatibilities with MariaDB Enterprise Server. It performs tasks, such as:

  • Upgrades the system tables to support any new features.

  • Attempts to repair tables with incompatibilities.

Problems can sometimes occur during upgrades. When problems occur, you may need to restore the system from a backup or reload the data from its system of record. Prior to upgrading, it is recommended to perform a backup or ensure that the system of record is available.

In 10.4 and later, the mariadb-upgrade utility can be executed as either mariadb-upgrade or mysql_upgrade.

In 10.3 and before, only the mysql_upgrade name is supported.
