Are there any trade-in programs for customers that own perpetual V-Ray/Phoenix FD licenses and want to move to the V-Ray Collection?

A holder of a perpetual license for any V-Ray and Phoenix product* can upgrade to a new Collection subscription at any time. The customer will be offered a 15 % discount for the first year of their new subscription. After the first year, the customer will pay the regular annual price for the Collection to renew his subscription. The original perpetual license will remain active. This offer only works on a 1:1 basis; 1 perpetual license gets discount to 1 V-Ray Collection subscription. 

*VRscans and V-Ray Render Node licenses are not eligible.
