Paid original version of Nik Software (pre-Google) -- how to upgrade?

Quite a few years ago, pre-Google purchase of Nik, I purchased a license and product key for every single product in the Collection, one by one over a two-year period. (yes, I know - expensive)

Am I eligible for the upgrade deal? And if so, how do I do that transaction? The process looks like it’s locked in to people who have paid DxO money.

Any suggestions?

You’ll have to buy the set, 99$ right now and you’re all set with the 7 plugins.
