Is it possible to convert a private orb to be public?

I understand that it isn’t possible to make a public orb private, since that might break existing workflows. But I’m interested in turning my private orb public.

The lack of support for circleci config validate with private orbs means that I can’t really use private orbs. So, I would like to convert my orb to be an unlisted public orb. But I can’t find any documentation on this. Is it possible?

Thanks!
