You can copy a configuration that you've done on a product to another product (or more products).
Once the product has been duplicated, you can change any settings, meaning that you can use the duplicate option as starting point to create new configurable products.
How to do it
- From your back-office, click on Products, locate the product from which you want to start and click the Clone Product button.
Select one or more target products on which you wish to duplicate the same configuration of the first product.
