I beg to differ on that. I have upgraded "in place" for many years
without any issues whatsoever. The clean install is a last resort.
If the system is clean and running well and everything is up to date,
an "in place" upgrade will not be an issue.
FWIW to the OP, unless there is a dire need to install native via
Bootcamp, i.e. highend gaming or any very highend graphical
application, it will be much easier to just use the virtual machine
approach. The added bonus is that you never leave OSX and
the "Windows PC" will just be an application in OSX with its own
window.
