I had a small discourse forum for a few years and it works well. I set up autobackups, but didn’t update discourse version for a long time.
Server died, but I have backup. Backup is from the old discourse version, about a 2 years ago. When I’m trying to install the newest version and restore from backup, it doesn’t work. When I’m trying to install old version, it isn’t possible: setup script automatically pulls new commits and latest docker image, I even found these lines in launcher script and deleted, but some internal code in docker image also checks and updates git to latest version.
What should I do? How can I run old discourse version or restore old backup on a new version?
