New branch in mirror (migrated) repo?


I’ve succesfully “migrated” an open-source project (from upstream’s own git) into a pull mirror. Everything worked, all the original branches and tags were copied, so far so good.

If I create a new, unrelated branch in my gitea repo, will it stick around? I’m afraid it might be dropped the next time syncs my “mirror” with upstream (since upstream obviously doesn’t have my branch).

My goal is to set up a mirror of the upstream so that I can develop and contribute back — but still have automatic updating of upstream branches.
