When to extend toilet flange?

Right now we have the subfloor that the toilet flange is screw to, a thin layer of ditra and tile then the toilet sits on that. We're thinking of taking the toilet out, raising the floor a bit to be level with the main floor then putting vinyl plank flooring down and reinstalling the toilet.

With that said the toilet flange will now be sunken a bit under the top layer of vinyl before we install the toilet again.

Would it be best to cut the flange and reinstall it on the last layer of plywood so it protrudes above the vinyl floor or would a double wax ring work just fine?

In most cases up to a 1/4 inch above or below the surface will be OK. But I suggest you buy a flange extender. They come in 3 different thickness. This should raise your flange to the level of the floor. Although a double wax ring is a common trick I don't prescribe to it only because you're making do with a poor installation.
