New build with old SSD

To my understanding, it's best to do a fresh install of windows when you're moving to a new motherboard. (For reference, my current build is an ASUS P8Z77-V LK with an i5-3570K, new build is going to be Asus Z170-A with i5-6600K)

I have an SSD (Crucial M4 128GB) and an HDD (WD Black 1TB) from my current build I'd like to use in the new setup (and I'm adding a second SSD, Samsung 850 EVO 250GB).

Currently, my SSD is using Windows (7 Home Premium x64) with some smaller programs, and my HDD houses everything else.

Ideally I want to use the old Crucial M4 as my Windows drive again, but have it as a fresh install, upgraded to Windows 10. Unfortunately I no longer have my physical copy of Windows 7 (pretty sure I left it with my mom when I moved, but she can't find it)

One of my friends suggested how to go about doing this:

- Backup files from SSD
- Upgrade system to Windows 10, since it's still free to do for another month
- Use MagicJellyBean to get my Win10 CD Key
- Wipe the drive
- Put together new machine
- Boot without drives
- Set BIOS to UEFI, reboot, shut down
- plug in SSD
- Install Win10 via USB

Apparently I'm bad at Googling, because I honestly cannot find anywhere that explains how to safely delete everything off an SSD that also runs your OS. I'm pretty sure everything else I can do without problem.

Unless, of course, there's an easier way to go about doing this. Any and all help is appreciated.

No. The 'license key' you get after Upgrading to Win 10 is irrelevant.
1. Discover your current Win 7 license key first.
MagicalJellyBean or Belarc Advisor.
2. Install Win 10 on the new hardware, and use the Win 7 license when it asks.
UEFI, AHCI and all that jazz.

It may make you call MS for the license key.
You may try to connect the M4 SSD into the new build, the PC should boot, but you will need reactive the win7 by phone.
After that, make sure your win7 with sp1 is up to date, and make a whole win7 backup image, then upgrade to win10. After that you don't need the win10 key anymore for the clean re-installation, because microsoft has the info in their server. But you can get the key if you want.

Recommend to download the win10 ISO, and put it into either USB or DVD for upgrading from win7. https://www.microsoft.com/en-us/software-download/windows10

Just checking to make sure I'm clear -- is it possible that I don't need to upgrade windows on my current build at all, I can just plop the SSD as is on the new build and do a fresh install of Windows 10 via USB?

Correct. The license issue is the same either way. Either it will or it won't activate, and may require a call to MS.
But a clean install on the new hardware is best for the operation aspect.
During the install, you use your existing Win 7 license key.
