I'm about to unleash a Core Data-based application, and I'm sure the
schema will change in later versions. The Core Data Model Versioning
and Data Migration Programming Guide seems to say that migrating a
store from one version to another, at least in simple cases, is
magical: The application embeds the historical MOMs, with one of them
marked "current," and when a store built to an earlier model is
opened, it is (in SIMPLE cases) migrated to the current model.
Is this the case?
In that event, is it necessary to do anything at all (other, perhaps,
than attaching a version string for human consumption) in version 1 to
prepare for migration?
