Changing order status without sending emails

Q: Is there a way to mark a large amount of orders as completed, without having the site auto-send a bunch of emails. I don’t really want to disturb any of my clients or confuse them about past orders, but I do want to change their status. These orders are orders that were finished but never changed the status…

A: Wwice in the jigoshop_emails.php file comment out the action:

 add_action('order_status_pending_to_completed', 'jigoshop_new_order_notification');
