Lightweight Migration with RestKit
===

Apple's docs give the following example for setting up an (automatic) lightweight migration:

    NSError *error = nil;
    NSURL *storeURL = <#The URL of a persistent store#>;
    NSPersistentStoreCoordinator *psc = <#The coordinator#>;
    NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:
        [NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption,
        [NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil];
     
    BOOL success = [psc addPersistentStoreWithType:<#Store type#>
                        configuration:<#Configuration or nil#> URL:storeURL
                        options:options error:&error];
    if (!success) {
        // Handle the error.
    }

However I am using RestKit, which handles the creation of the persistant store behind the scenes. A simplified version of my initialisation code looks like this:


    // Initialize RestKit
    RKObjectManager* objectManager = [RKObjectManager objectManagerWithBaseURL:rootURL];
        
    // Create the object store
    objectManager.objectStore = [RKManagedObjectStore objectStoreWithStoreFilename:databaseName                 
                                                                     usingSeedDatabaseName:seedDatabaseName 
                                                                        managedObjectModel:nil //Don't need to pass it in. It is infered  
                                                                              delegate:self];
    // Create Mappings
    ...
    
    // Define Relationships
    ...
    
    // Set Mappings
    ...

Where should I pass in configuration options given that RestKit creates the persistantStore behind the scenes?
