Magento 2: How to change order status from Complete back to Processing

Question

Is there a way to change the order status back to being Processing when order is already in Complete status? Is there some code way or MySQL way to achieve this?

Answer 1

There is no built in way to do this. If you manually alter the database status data for the order you will break the order / invoice / ship core logic of Magento and although you might change the admin order status it is likely to other cause problems or errors for that order.
