I'm looking to do this too as i'm investigating a way to migrate from a free app + paid purchase to a free app + IAP purchase. However as 3c said, simply doing the check from another app won't work as that will result in a ERROR_INVALID_PACKAGE_NAME error.
Anyone else ever migrate from a separate paid version to IAPs? How did you manage it?
