Overview
The mysql_upgrade utility examines the data directory for incompatibilities with MariaDB Community Server 10.3. 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.
MariaDB Community Server 10.3 does not provide a symbolic link to the utility's new name (mariadb-upgrade), so the legacy name must be used.
