Really no one should need to do a clean install any more than once anyway. Unless of course like many in IT you appear to enjoy having to reinstall everything over and over again

How I will be doing things on July 29th

Take a system image of my working 8.1 pro

Upgrade to 10 take a system image.

Recover to clean install update and install any drivers then take a system image

Install all applications and take a system image

With all these in place I can mess around with any of the install run tests on different applications and if anything goes wrong I have a choice of where to recover from. Once I am happy everything is working I can get rid of some of the images until this point I will keep everything. I will then back up my fully working windows 10 install to a couple of places so it is safe as well as keeping a local image. With this hardware then I will never need to run a clean install as can easily recover to a fully tested working system in minutes
