The datadir located at $datadir needs to be upgraded using 'mysql_upgrade' tool. This can be done using the following steps:

  1. Back-up your data before with 'mysql_upgrade'
  2. Start the database daemon using 'service mariadb start'
  3. Run 'mysql_upgrade' with a database user that has sufficient privileges
