Bulk project migration - merge 2 GitLab CE servers

My use case: I have 2 GitLab CE servers with hundreds of projects each. I’m managing a company merger, and each company has their own server and we’re looking to merge them into a single one.

I saw this post and got hopeful…

But it led me to this documentation…
http://docs.gitlab.com/ce/user/project/settings/import_export.html
Which seems to indicate that I’d have to export and import each project manually. If I have to, I will - but I’d rather avoid it if I can. Is there a way to bulk export/import?

Thank you!
