I am sorry to hear that you have experienced such issues while upgrading your projects.
John, this is a new issue we haven't encountered till now. Also I did not succeed to reproduce it. Could you give it another try and then get back with information what happened. If it still does not work it will be best if you could open a ticket and send us a project reproducing the issue.
Carl, can you please provide some more information about the problem you have with the Upgrade wizard.
Thank you for your cooperation.
