I have an app Im moving over to cloudkit and it works fine on a new instance, but updating to this instance causes a perpetual crash and requires reinstall. I know this is because the persistence object changed. I was just using a normal NSPersistentController now a CK one, and there are two persistent stores, the public and private stores. Is there a way to either migrate the data properly, or atleast wipe the data model before it crashes and have it start anew? (I dont have many users and I know them personally so this would be acceptable)
