Importing from gitlab.com to GitLab EE fails

Hi, I am trying out the GitLab EE.

How do I migrate projects from gitlab.com to GitLab EE instance?

I have done all the steps here http://docs.gitlab.com/ce/integration/gitlab.html

Then tried migrating individual projects, but all migrations end with "failed" status.

Once "migrated", repository has files but no commits and no issues.

I have looked through couple of logs but I cannot find any obvious errors.

In /var/log/gitlab/gitlab-rails/sidekiq.log logs I can see:
