The task you describe, at least the part where no whole brain transplant is involved, can be divided into two parts: 1) extracting the essential information about your mind from your brain, and 2) implanting that same information back into another brain.
Either of these could be achieved in two radically different ways: a) psychologically, i.e. by interview or memoir writing on the extraction side and “brain-washing” on the implanting side, or b) technologically, i.e. by functional MRI, electro-encephalography, etc on the extraction side. It is hard for me to envision a technological implantation method.
Either way, it seems to me that once we understand the mind enough to do any of this, it will turn out the easiest to just do the extraction part and then simulate the mind on a computer, instead of implanting it into a new body. Eliminate the wetware, and gain the benefit of regular backups, copious copies, and Moore’s law for increasing effectiveness. Also, this would be ethically much more tractable.
It seems to me this could also be the solution to the unfriendly AI problem. What if the AI are us? Then yielding the world to them would not be so much of a problem, suddenly.

I would expect recreating a mind from interviews and memoirs to be about as accurate as building a car based on interviews and memoirs written by someone who had driven cars. which is to say, the part of our mind that talks and writes is not noted for its brilliant and detailed insight into how the vast majority of the mind works.
I suppose it boils down to what you include when you say “mind”. I think the part of our mind that talks and writes is not very different from the part that thinks. So, if you narrowly, but reasonably, define the “mind” as only the conscious, thinking part of our personality, it might not be so farfetched to think a reasonable reconstruction of it from writings is possible.
Thought and language are closely related. Ask yourself: How many of my thoughts could I put into language, given a good effort? My gut feeling is “most of them”, but I could be wrong. The same goes for memories. If a memory can not be expressed, can it even be called a memory?

Good point.
