Upgrade Procedure

[tep1997]

What is the proper way to upgrade without losing historical data? I just ran a docker compose down and then docker compose pull to upgrade to newest. When it finished, I had the new version but no historical data.

Hi @tep1997 , your postgres container is meant to have its data volume either mounted or not removed when your doing docker docker compose down. if the volume is removed or the data path is not mapped to a local path, the data will remain inside the container and just reset when the container is replaced . Specifically /var/lib/postgresql in your postgres container needs to be mounted

Found it. I had an incorrect mount syntax pointing at an old Portainer instance from a recent migration. All good now, thanks!
