Yes. But this is a lot. It may be easier to use Forgejo’s built in migration tools, to copy over repositories along with their issues and other info. You would have to rebuild the admin parts of the site, like “organizations” and user privileges. (Well if you are using oauth and mapping users from oautb groups then you don’t…). And I don’t know if it’s automated for a many, many repos. But it’s just a click click click in the gui.

I remember there was a tool, I think it was related to forgefed, that could do batch repo migrations via the cli. I can’t find it anymore though.
