Migrating old self hosted gitlab to gitlab.com


I’d like to migrate pretty old self hosted Gitlab CE 9.0.13. Unfortunately it’s installed from source, so upgrades themselves are quite a pain. I’ve read I can:

  • migrate just repos
  • use export/import tool (but versions should be compatible, so it’s off the table)
  • tweak api

Any ideas how to migrate all the data in best case scenario? Or migrate at least most of it in some easy way? Could paid/bronze support help me with that?

Thanks a lot for any response!
