I currently have a working bitwardenrs:server running on my Synology in a Docker container, is my assumption that I can just download and install the vault warden docker container, point it to my data folder and be good to go?
Or is there something else I need to do?
Nothing else you need to do.
Just use the other container/docker-hub name and you are good to go.
After a bunch of backups, I did exactly as you recommended and it fired up no problem. The only thing I did was change the proxy port slightly. I didn’t want to remove my bitwardenrs container (yet) until I’m sure this one works without issue and I couldn’t have two containers on the same port.
