After further research I determined that this problem occured because I didn't set the source type and destination type. I will fill a bug report about the message not containing enough information (by the way, I'm running 10.5.6 as this is my target platform, this might have been solved since that).
However, the reference for 'NSMigrationManager' indicated that possible values for "type:" are specified 'NSPersistentStoreCoordinator' Reference. Based on that I assumed (as it was not indicated), that the accepted values would be the same as in "addPersistentStoreWithType:" which nil is a valid value (though not documented as valid). I'm wondering if I should also file a documentation bug about the fact that nil is not valid in this context or never valid (this works, but I should not rely on this behavior). Or if this should be supported, and then I should file a behavior bug.
