Delete All Magento Test Orders

This step is done only on new store which are ready forproduction and don’t have any “Actual Orders” in the system. I would highly recommend taking a full backup before you proceed. Basically when you run the following queries on your Magento database it will complete wipe out all the records and reset the order counters. If you are about to indulge, then please make sure that you know what you are doing.
