"Will I be able to upgrade my perpetual license to a new perpetual license or renew my upgrade subscription?
No. Major version upgrades for perpetual licenses to new perpetual licenses will no longer be offered as of November 2, 2015. As an existing customer, you will be able to switch your perpetual license to our new subscription based model with a discount."
