Title says it, I upgraded my system from a 2disk mirror to a 4 disk z1. I did not dump my Immich DB ahead of time. I did copy it over though. I have the pgdata folder. Installing the app throws errors probably due to pg version 15/18? Is there any way to get my db upgraded or install the older version of Immich using the old db and then upgrade?
