# Manual MySQL upgrade

## Run a manual mysql_upgrade

This step is usually not necessary.

    docker-compose stop mysql-mailcow watchdog-mailcow
    docker-compose run --rm --entrypoint '/bin/sh -c "gosu mysql mysqld --skip-grant-tables & sleep 10 && bash && exit 0"' mysql-mailcow

As soon as the SQL shell spawned, run `mysql_upgrade` and exit the container:

    mysql_upgrade
    exit
