Therefore, it may be possible to transfer consciousness into an android by either slowly replacing the components of the brain with machine counterparts, or by connecting the brain to a machine replica with components that would come online as portions of the brain were shut down. This android brain would have to be made to function exactly the same way as the human brain, but with greater processing power and memory storage space.

...Or we could just create sentient machines to run the place for us and figure out cures to all diseases--including aging.
Actually, not all parts of the brain gets changed during a normal human life. Also, it's the structure and the connections between the neurons that make up our brain, it would be much easier, I think, to just scan this structure and create a computer simulation of it, that to do what you suggest.
