The downside of copying your brain is that it’s a copy, you’ll have your original meat body and a separate mechanical body which minds which immediately start to diverge. They’re both still you, but meatman gets no upgrades. You could destroy your meat body as part of the transfer but then it’s reasonable to say you’re dead with a robot that thinks it’s you.
The closest you can get to a proper transfer would need an implant which works similar to how your body naturally replaces cells, the implant would gradually take over neurons until you have a fully mech brain which can be transplanted to a new body. You could argue that’s still just a destructive copy but I think it’s within most people’s tolerance.
