Upgrade Docker Container failed

Hi guys,

so i have a private Gitlab with only one Project. Last week i pushed something into that project. At the weekend i tried a upgrade to version 15.11.x. I think my last Version was 15.7.3. But at every Upgrade attempt, it failed with the message: “It seems you are upgrading from major version 12 to major version 15.”. I forget to pull my last push at my new device and my old device is broken.
If i try to strt the old gitlab version, the same failure message appears.
Do you have any solution to get my old gitlab version running or get my last push?

I run docker with that command:
docker run --detach --hostname xxxx --publish 10443:443 --publish 10080:80 --name gitlab${gitlabversion} --restart always --volume $GITLAB_HOME/config:/etc/gitla
b:Z --volume $GITLAB_HOME/logs:/var/log/gitlab:Z --volume $GITLAB_HOME/data:/var/opt/gitlab:Z --shm-size 256m gitlab/gitlab-ce:${gitlabversion}-ce.0

Thank you!
