--- title: Fix order.created_by_id constraint issue: NEXT-16139 --- # Core * Added `\Shopware\Core\Migration\V6_4\Migration1625819412ChangeOrderCreatedByIdConstraint` to change the FK-Constraint on the `order.created_by_id` column and `order.updated_by_id` to `ON DELETE SET NULL`, thus allowing that users, who created or edited admin orders, can still be deleted.
