In your thought experiment where your mind is transferred into a simulation and simultaneously ceases to exist in the real world, I don't think we need to update the concept of "you" for most contexts, and certainly not for the context of answering the question "is it okay to kill you?"

Asking if it's "still you" is pretty similar to asking if you're the same person you were 20 years ago. For answering basic questions like "is it okay to kill you?" the answer is the same 20 years ago and now: of course not!
