I have only 3 folders of data that were generated via docker.

/etc/gitlab
/var/log/gitlab
/var/opt/gitlab

I don't remember which gitlab-ee version I used and any version always fails running.

I don't have time to waste debugging gitlab.

How can I find the version of my files so that I can run the right version without having to migrate my data and failing.

Note: None of the answers under How to check the version of GitLab? is possible in my case, I don't have /opt/gitlab. I'm also surprised Gitlab's guys didn't think it was a good idea to display the version of the data before automatically migrate...
