ps. one special problem I have is that I don't want the migration to

"If your application does support versioning and you choose to use
custom version skew detection and migration bootstrapping, before
opening a store you should check (using
isConfiguration:compatibleWithStoreMetadata:) whether its schema is
compatible with the coordinator’s model: if it is, you can use
addPersistentStoreWithType:configuration:URL:options:error: to open
the store directly; if it is not, you must migrate the store first
then open it (again
usingaddPersistentStoreWithType:configuration:URL:options:error:)."
