I want to do migration with 2 core database.
I have read apple developer document.
For the first database, I add some attributes (string, integer and date properties) to new version database. And follow all steps, I have done migration successfully with the first once.
But the second database, I also add attributes (string, integer, date, transformable and binary-data properties) to new version database. And follow all steps (like the first database) but system return an error (134130).
Here is the code:
if (persistentStoreCoordinator_) {
PMReleaseSafely(persistentStoreCoordinator_);
}
// Notify
NSNotificationCenter *nc = [NSNotificationCenter defaultCenter];
[nc postNotificationName:GCalWillMigrationNotification object:self];
//
NSString *sourceStoreType = NSSQLiteStoreType;
NSString *dataStorePath = [PMUtility dataStorePathForName:GCalDBWarehousePersistentStoreName];
NSURL *storeURL = [NSURL fileURLWithPath:dataStorePath];
BOOL storeExists = [[NSFileManager defaultManager] fileExistsAtPath:dataStorePath];
//
NSError *error = nil;
NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:
[NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption,
[NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil];
persistentStoreCoordinator_ = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:self.managedObjectModel];
[persistentStoreCoordinator_ addPersistentStoreWithType:sourceStoreType
configuration:nil
URL:storeURL
options:options
error:&error];
if (error != nil) {
abort();
}
error is not nil and below is log:

I try a lot of solutions but it does not work.
I just add more attributes to 2 new version database, and succeed in migrating once.
Thanks for reading and your help.
