ESRS_DE-3.50.00.06.bin docker image will not upgrade

Hi,

I'm running esrs_de-3.48.00.04 in a docker container. The upgrade from 3.46 has worked, but now I'm trying to upgrade to the new version 3.50.00.06. I'm running the following command:

# ./ESRS_DE-3.50.00.06.bin --upgrade
Installed ESRS Docker image is esrsde:3.48.00.04
Upgrading ESRS Docker to esrsde:3.50.00.06
...
Extracting...
Stop esrsde container
73e862b7755a
Backup esrsde data container volumes to /root/esrsde.194385
Start esrsde container
esrsde-app

It finishes without an error, but afterwards it's still runnning the 3.48 version. What's wrong?

Thanks

Dirk
