After activation there will be a Split icon in wp-admin > WooCommerce > orders list page within the order actions. Splits all order metadata and product data across into the new order ID. Order is created and a note is left in the new order of the older order ID for future reference. Order status is then set on hold awaiting admin to confirm payment.
In stock/out of stock (If this option is selected, plugin will separate in stock and out of stock items. So items will be grouped as in stock items in one and remaining items in other order.)
