I have an old app on app store that is divided into one free version for both iPhone and iPad and one paid version for both, so four different apps in total. I am going to make a complete new version of it so that it gets easier to handle. I want it, if possible, to be one universal app that maybe can use in-app purchase for customers to get the "premium" content.
However, people have paid for the previous version, is it possible to somehow let them have access to the premium content in the new one? Or do you think that it is better to make a complete new app with another name? :P Any suggestions?
They can still use the old one if I remove it from app store right?
