How to Use GitLab Migrations

Hello Gitlab community,

I am facing the following challenge, and I really appreciate some help.

Currently, I have a GitLab instance the version is Community Edition 8.17.6. I would like to create a new GitLab instance (probably Community Edition 15.0.0) and move all the data from the oldest to the newest instance. In the following cases, I used Community Edition 15.0.0 as docker with image

Firstly regarding the existing projects (Repositories):

  1. I tried to import them using the option Repo by URL but , unfortunately, cannot retrieve the Git repository at this URL

In addition, I would like to import the groups and the users from the oldest version if this is possible.

I really appreciate some help with those issues. Thanks in advance for your time and your collaboration.

Best regards,
Panagiotis Parthenis

I have the same problem.
I created a new instance of gitlab-ce running with docker and i’m trying to import some projects from an old instance, but with the same result as yours: There is not a valid Git repository at this URL. If your HTTP repository is not publicly accessible, verify your credentials.

Just to add some info: i can git clone the project from the remote host from inside the gitlab docker container.

One solution is to create a empty project in the new gitlab, git clone the desired project from the old instance, change the remote origin to the new host, then push.

Access “Admin → Settings → Network → Outbound requests”
Check “Allow requests to the local network from web hooks and services”

This solved for me.

Why not upgrading the previous instance to 9.x, 10.x, 11.x, 12.x, 13.x, 14.x and then 15.x and migrate from the old one to a new one to use 15.x? It looks too dangerous to me. Document says similar. Just at your own risk.

Dear @ulisses ,

This solution also works for me too !!!

In addition, for my case, I should set the proxy inside the file gitlab.rd.

I really appreciate your help !!
