Hello, I’m currently searching for a safe procedure to upgrade my Mautic installation to the new version. Previous attempts to load newer images (5.2.4+) always resulted in corrupted databases and backup restores. The Docker configuration exists of 4 separate containers (mautic\_web, mautic\_worker, mautic\_cron and db) running apache. Since all containers are interconnected, including health checks, it’s not just a question of conserving the volume directories and pulling a newer image. Until now I’ve been unable to find a proper explanation on how to upgrade. Is there someone accustomed with the Docker configurations? I really could use a helping hand here… With more than 3.300 contacts alone I really want to prevent losing everything… ---

I’ve installed Mautic outside Docker natively on the server. This post can be closed.
