Hey @lilap, I’m not 100% sure I follow you. This sounds like you’re going to delete all orders: “I would like to remove the plugin with existing orders that have order numbers which were made by this plugin.” but then the next point makes me think orders would remain: “If I were to uninstall and delete the plugin, will there be any issues with those existing and still active orders?”
Do you plan to remove the existing orders? When uninstalling the plugin, as it’s no longer showing its modified version of the order number, all orders would then revert to using their WordPress post ID instead (whatever the number would have been without this plugin). So if you’re deleting those orders as well, there should be no issues, but if you plan to keep them, you should note that the order numbers may change for existing orders and revert to using the order ID instead.
thanks!
Beka
