So order of action is to uninstall 2013 with the AutoCad uninstall and then download this upgrade?
It doesn't matter, but I'd suggest you download installer at first, than proceed with removing of existing installation.
In order to save your personal settings of the existing AutoCAD installation you need to leave this:
