Yeah, I think we need a Jira to improve CM project upgrade to not save a project on upgrade until a user clicks save explicitly. The way it works right now is the way we always did upgrades (which is not to say it is right). I guess I never cared myself that much, as all my projects are under version control, even if it is a local git checkin.
