All customers with licenses with non-expired Upgrade Subscription can continue using the purchased products and receive benefits according to the original license terms (e.g. receive free product updates).
Once the upgrade subscription term ends (after November 2, 2015), there will be no option to renew the existing upgrade subscription. However, a discounted price will be offered for switching to our new subscription-based licensing model.
Please make sure to check the requirements for Existing Customer Discounts.
