I concur that Prepar3D v2.1 + HF (hotfix 1) + legacy mode using the Estonia Migration Tool makes the CS 777 work again, but I am not seeing any frame rate improvements in CS 777 V1.3 above Version 1.2. Has anyone else used CS 777 in Prepar3D v2.1 + HF (hotfix 1) and claims improvements in FPS, or is it only in FSX that you are likely to realise any benefit?

I don't know what computer system you have, but I did try CS 777  once around the pattern.  Boy, you better have a strong computer for P3D and CS 777.  I got i7 920 @ 3.2 ghz and GF 560ti.  I would think that's bare minimum.  When I tried it, I realized I needed a new setup.
