How to update Gitlab 9.0.5 to latest version?

Question

GitLab

The problem is this: there is now a deployed Gitlab 9.0.5 ee, a postgresql 9.6 base, OS CentOS 7. The task was to update it to the latest version.

What the problems did:
We raised another server on CentOS 7, installed postgresql 11, installed gitlb 9.0.5, migrated projects and database, everything worked.

We started updating to version 9.5.5, etc. as written in https://docs.gitlab.com/ee/policy/maintenance.html... 500 error after update.

We rolled back to version 9.0.5, made the script update step by step through all versions. He got to version 9.1.10, updated to version 9.2.0 and again 500 error. We tried to immediately upgrade to 9.2.6, 10.10.x - also 500 error.

If anyone has experience updating this, please tell me how you did it. Thanks in advance.

Answer 1

Thanks to all!
Solution:
gitlab-rake db:migrate:status
If there are lines with down in the output of the command, then do gitlab-rake db:migrate and check again.
then
gitlab-ctl reconfigure
gitlab-ctl restart

It's better to update slowly and by minor versions ....
Plus, as far as I remember, they changed the address of the repository not so long ago, check that this is not the problem
. Also, it is not clear from the question what installation method you have. Well, 500 then who gives an error?
