Well, this keeps me from upgrading to F7!

How serious a problem results from doing an installer upgrade from FCx to
F7, no repartitioning?  Is it going to cause massive data loss for
unsuspecting users, or does the Anaconda notice and stop the process?
Would a respin be needed to get the installer to work for them (me)
(assuming they recovered from the first upgrade attempt)?
