Upgrade gitlab-ee from 14.1.8

Hi, I successfully upgraded my old Debian based gitlab-ee 13.12.15 to 14.1.8 using docker.
I backed up 13.12.15 on the Debian.
Constructed a brand new Rocky Linux based docker engine.
Installed gitlab/gitlab-ee:13.12.15-ee.0 and restored my previous backup.

I repeated the docker processus like described in gitlab’s doc :

stop docker image
rm docker image
run newer docker version image
backup newer gitlab

doc says to use this path : 13.12.15 → 14.0.12 → 14.3.6 → 14.9.5

but migration 14.0.12 → 14.3.6 makes docker restarting the container again and again without finishing the job.

I tried 14.0.12 → 14.1.8 successfully.
But then, 14.1.8 to 14.2.0 fails and once again makes docker restarting the container again and again without finishing the job.

Does anybody know where to find the original error ?

Following my own post. I finally had a chance to successfully migrate du 14.2.7.
Thanks to Upgraded to 14.1.8 but have pending migration

Finally done!

FYI, my upgrade path was finally :

13.12.15 → 14.0.12 → 14.1.8 → 14.2.7→ 14.3.6 → 14.9.5 → 14.10.5 → 15.0.5 → 15.5.6 → 15.9.0
