No, it won't be installed "over the old one", it will be installed
_in_addition_to_ the old one.  the old Emacs binary will still be
available, and all the support files will still be there.

Why did you say "over the old one", and what did you think would
happen when such an installation is done?  I think you might be having
an inaccurate mental model of what happens when a new Emacs version is
installed "over the old one".
