In my case, an order should be modified after the review.
Order items can be removed or quantity will be modified from the order.
I knew the Re order would the do the purpose by manually deleting the old order once re order is completed. But I do not want to change the order id.

It too bad idea to
change order item and order details,delete order
after order placed.As per as magento system ,there lot of calculation likegrand total,subtotals,tax,shipping cost
are depends on order items.If you will done
any change at order items and delete items
then it will create huge issues on calculation sales.So it will better idea to you create an new order for this case and cancel old order.
