Consequences of a change in privacy level
Converting an open group to a private group restricts access to content to authorized members only. Users who were members of the open group become members of the private group. You will need to invite other members to your group to allow them access it. If this group is a visible private group, other users will be able to request access.
Converting a private group to an open group allows all users within your team/organization to view the group's content and join it in order to contribute.
