We have an organization which is billed as GitHub Team right now ($25/month). We have 3 contributors in the organization. I’d like to downgrade to a free tier due to some changes. Since beginning of 2019 Private repositories can be free up to 3 contributors. But when I’m looking at our billing it’d say “Downgrade to Team for Open Source”. We have some open source repositories, but I still want to keep the 7 private repositories.
If I’d downgrade, would those become public? If yes, can I convert them back to private due to the recent changes early this year? How should I go about this?
