Trying to upgrade to latest version from BWrs

I have bitwarden rs in Docker on a Raspberry Pi that needs updating to the latest vaultwarden so the new clients can connect. I am new to Docker, but can follow instructions. Unfortunately search results are not synching up to what I have.

I followed instructions from another post (Updating the vaultwarden image · dani-garcia/vaultwarden Wiki · GitHub). When I rebooted docker didn’t show any containers (fortunately I cloned the disk image and am not missing anything). Is there a step by step for going from bitwarden rs to the latest vaultwarden on a Raspberry Pi with Docker?

Edit: Got my image back on the Pi. The container I have is:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
xxxxxxxxxxxx bitwardenrs/server:latest-arm32v6 "/usr/bin/dumb-init " 2 years ago Up 31 minutes (healthy) 3012/tcp, 0.0.0.0:8080->80/tcp bitwarden

Connecting to the BW login page shows:
