It wouldn't be you, it would just be another person with the same memories that you had up until the point the copy was made.

When you transfer a file, for example, all you are really doing is sending a message telling the other machine what bits the file is made up of, and then that other machines creates a file that is just like the original - a copy, while the original still remains in the first machine. Nothing is even actually transferred.

If we apply this logic to consciousness, then to "transfer" your brain to a machine you will have to make a copy, which exist simultaneously with the original you. At that point in time, there will be two different instances of "you"; and in fact, from that point forward, the two instances will begin to create different memories and experience different things, thereby becoming two different identities.
