Re-numbering my Product IDs

Running WordPress 3.8, latest version of Woocommerce. All I need to know if how to re-renumber my products. I see a PID by the name of the Product. But there’s no option ANYWHERE to change it that I could find. I figured, surely somebody else has been down this road. If that’s you and you can help me, that would be great.
