Yes, but the real question here isn't 'can consciousness be copied' but 'is a copy the exact same as the original in all aspects'? Would the continual and dynamic awareness from the point of origin continuous still continue into the duplicate, in such a way that the awareness (original) didn't simply cease?
I look at it like this: if I copy a program on my computer, I'm making a duplicate somewhere else. Then, I have two copies of the same thing. Naturally, I could delete the other copy with no ill effect for anyone or anything - but suppose the duplicate were flawed, and I didn't know it (this happens, you know) - or suppose that these programs had self-awareness. Now, whether I duplicated the program or not, whether it was a perfect copy or not, would have no effect whatsoever on the original. As long as I didn't delete the original, it would still have life and limb and whatever else it has. But if I delete the original, the duplicate doesn't suddenly become the original; the 'self' isn't magically transferred, only copied.
If I 'move' a file on my computer, all I'm doing is copy and delete, really. Same problem.
But if I move a person, I'm not copying a deleting.

OK, I'm rambling. Sorry.
