How can I change a product in someone's subscription?

I need to change a product for an existing subscriber, how do I do that?

You can either delete the product and add in another, or swap your customer's subscription product with another product. In order to swap, the products must belong to the same subscription group. If they do not, you can change the product's subscription group for just that customer.

Note: Removing a product is only possible if the customer has more than one product in their subscription. If the customer only has one product, you can add in the new product first and then delete the other.
