Permanent license for Legacy Substance Products

I have(had?) a permanent license for Substance Designer, Substance Painter, Substance Alchemist, etc. 
This permanet license was purchased just before the Adobe acquisition.

I'm at a loss as to what happens with my legacy Substance products and how they'll continue to operate in the future.

While I am aware there is the option to migrate to Adobe's ecosystem of products, my question regards this migration as another topic. I am only interested in keeping the permanet license and products I already own.

I have an account with Adobe, of course. I have(had?) an account with Allegorithmic.

Thank you so much for anyone willing to respond. You have my appreciation.
