Import local git

Is there a way to import my repos directly through the file system?

Or can I re-enable the ssh service of my original git server so that I can then import them into gitlab? I’d probably have to disable ssh service in gitlab first, and then reconfigure the git user to use the original home dir again. I’m afraid I’ll just break more stuff if I try this on my own. Some guidedance would be appreciated.

Ideally, I’d prefer to just move my existing repos into the new repo. But where is it, and would that work?
