Reply To: Subscription renewals not getting the discount
You shouldn’t experience any changes switching over. You’ll just want to confirm your variations and other product data.
After saving the product (to store it as a variable subscription product), you can trigger the update to existing subscriptions by editing a variation. The fact that it’s now a variable subscription product type shouldn’t have any effect on applying the new subscription changes. Once the subscription is modified, it should recalculate accordingly, including the discount.
