You will "likely" be able to just type in the install key and validate the
system. The version you end up buying must exactly match that which you
already have installed on your computer. If you have Ultimate on your
computer you must purchase Ultimate to get a valid key.
Of course, all this is speculation, as no one has done this. Remember, the
operating system has not been released for sale and no one has a legal
retail copy as of yet.
You are really on your own and have no one to complain to if the above
scenario fails to work for you.
