What the destination and source options in NSPersistentStoreCoordinator's replacePersistentStore: method for?

Hello!

Hello could anybody tell me plase, what the `destinationOptions:` and `sourceOptions:` in `-[NSPersistentStoreCoordiantor replacePersistentStoreAtURL:destinationOptions:withPersistentStoreFromURL:sourceOptions:storeType:error:]` for?

Does they matter at all in the case the destination store doesn't exist?

Thanks in advance,

Aleksandr Skobelev
