Yes it is. Orderimp was designed with a fail-safe that requires you to first import the orders into the app before it can delete an order from Shopify. This way you should always have a backup file. Just Export the orders from your store, then upload the orders you would like to delete into orderimp.
The import should come back with all the orders marked as “duplicate”. Then go to the orders page and click “Delete Range” (Check boxes for Delete Orders on Shopify Too and delete all available orders.Then filter by duplicates). Once the orders are deleted from your store, you can re-import the orders with your changes if needed.
