The upgrade process seems to use something like MDT – it gathers up all your files, registry settings etc. and creates an archive. It then puts down a new OS, and imports all your old files/settings. That’s what also allows the installer to do a roll-back, in case of problems, as all your old data/files/settings are still there.
I would do the upgrade first, so that you have an activated Win10 license. If run into issues after the upgrade, doing a clean install should require no product key. Not applicable if you are use Enterprise edition.

Went through the whole process two weekends ago, but on the desktop only with my developer's hat on (I have only used Win10 on a tablet for about 5 minutes). Some non-techie friends just look at it and go "it's sort of prettier isn't it, but where are my programs?" I explain the Start bar menu and tiles to them and off they go, and that's about it, they don't care about anything else. As a power Win10 desktop user, I find Wi10 to be Win7 with more pretty clutter to get in the way of what you want to actually do. Internally they both feel about the same and all of my old apps installed and ran okay. But everything takes more clicks and more navigation to find and run quickly in Win10. I spent hours and hours stripping Win10 back to look and feel like Win7. And I must stress that I didn't do that out of spite, or because I resist change ... I did it because I had to! Win10 contains so much worthless garbage and clutter that I had to strip it out to keep my productivity up. All tiles, flat apps, superfluous icons, wallpaper, plug-ins, Cortana, etc ... all erased or hidden. I've pinned the dozen apps I use every day to the start bar and I'm back to working normally. So the big question is ... why did I do that? Why was it necessary? I'm not the only one. Somebody in the marketing and art departments that produce Win10 must be slightly askew to reality. Win10 feels a bit like an unfinished iMac. So overall, I think you'll have little technical trouble going from 7 to 10, but as a power user I guess you'll spend a bit of time tweaking the desktop to your liking, as I did. GK
