Core data migration add fields problem

I have core data model and sqlite databse with data. Entity

 Bla:
    int:f;
    text:baar

and model class

@interface Bla {

}
@property(retain) NSNumber *f;
@property(retain) NSString *baar;
@end;
@implementation Bla
  @dynamic shared;
  @dynamic isEBird;
@end;

I add field BOOL:isGood to entity. I must do something to migrate to new version excluding set current model version to last version?

 @interface Bla {

}
@property(retain) NSNumber *f;
@property(retain) NSString *baar;
@property(retain) NSNumber *isGood;
@end;
@implementation Bla
  @dynamic f;
  @dynamic baar;
  @dynamic isGood;
@end;

I have error at app launch wher app migrate to new version 1
