## Run a manual mysql_upgrade

This step is usually not necessary. 

=== "docker compose (Plugin)"

    ``` bash
    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
    ```

=== "docker-compose (Standalone)"

    ``` bash
    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
```
