they should work, here's how it goes as far as I know. Ego Draconis saves will work in FOV. Ego Draconis saves will not work in the Ego Draconis version of DKS as it will tell you it's an obsolete save. If you've reached the end of ED you should be able to continue with that save in FoV, or if you already have FoV installed it should transition into it seamlessly
