We currently have two independent apps (one iPhone only and one iPad only) and want to migrate to a single universal app.
Does anyone know if it is possible to do this without killing off one of the apps? Someting like releasing an update to each app, containing the same binary?
Please link if I'm misssing this answered somewhere, thanks!
There is no current way to do this except by orphaning one of the apps, or continuing to support two nearly identical apps. You can't release identical binaries because each app has a different unchangeable unique App Identifier for that app embedded in the binary.
Some developers just leave behind the app with the least desirable set of reviews, ratings and popularity in category in the app store without any further upgrades. You could do something like change the name of the one you want to leave behind to "foo classic" or "foo legacy" as well as add some unobtrusive advertisements for the supported newer app to it.
