Why require an upgrade, you ask? When transferring a license to someone, that person tends to be new to Hedge. Starting with a legacy Hedge as the license isn't valid for the latest version is going to be a suboptimal experience. That's why we want new users to always start on the newest Hedge. Then, if a user needs help, we can be sure we and the user are not chased down a rabbit hole by something that has been fixed or improved upon long ago.
