You can debug the migration process by adding the launch argument -com.apple.CoreData.MigrationDebug 1 to your application. It should print out quite a bit of information.
In my case, my PropertyManager*-*.xcmappingmodel files are listed in the “Compile Sources” build phase for my application, so I can only assume they end up in the main application bundle.
The error message you are receiving is given when there is no migration found from the current Core Data model to some other Core Data model. This may happen if you accidentally modified one of the intermediate managed object models. I suggest you start with the above debug information and try to find out how far it is getting through the migration process.
Feel free to provide more details and I’ll see what I can do to help.
