I have two separate iPhone and iPad apps that I have now turned into a universal binary. I think I've done the hard part, but now I'm kinda stumped on how to submit that universal binary through iTunes connect in a way that users of the existing apps are prompted to upgrade. I know I could just submit this as an entirely new app and then pull the old stand-alone apps down, but I would lose the continuity of reports, reviews, and the prompting of the current users to upgrade....
Any tips?
