Hi Team,
 
I have run delta.
php -f bin/ubdatamigration run --step=4 --mode=update --limit=200 ssh
UPDATE `ub_migrate_map_step_5` SET `created_time` = ‘2000-01-01 00:00:00’ WHERE `entity_name` = ‘catalog_product_entity’; mysql
php -f bin/ubdatamigration run --step=5 --mode=update --limit=200 ssh
UPDATE `ub_migrate_map_step_6` SET `created_time` = ‘2000-01-01 00:00:00’ WHERE `entity_name` = ‘customer_entity’; mysql

php -f bin/ubdatamigration run --step=6 --mode=update --limit=200 ssh
