Import project into missing merge requests

I have a project I’m trying to migrate from a self hosted GitLab (11.6.3) to

Most of our other projects are importing successfully, however one is not working correctly.

The .tar.gz file is > 500 MB and after the importer does it’s thing all I get is a blank repo with no merge requests or issues. The only thing that has been imported is the project tagline.

After running housekeeping I can see activity, repo and when clicking on issues I get all of them but the number in the nav still says 0.

Biggest problem is none of the merge requests are being moved across.

Any ideas?

we’ve the same problem and cannot migrate a project with 280MB tar.gz file.
@wjdp any progress you could achieve?
