If I want to sell these licenses, what does the buyer need to have to use them? My guess is that either GR 5 Pro or GR 6 Pro will work with the RG 7 Pro Update. The GR 5 Pro Upgrade is older and it is unclear which of the several versions of GR 5 below Pro it would apply to. I haven't found a way to ask NI Support these questions directly.
Thanks
Answer - 7 Pro Update works for 4-6 Pro. Based on 7 Pro Upgrade requirements, it looks like 5 Pro Upgrade should work for the Elements and LE versions of 5.
