Windows 10: Wanting to Upgrade to Windows 10 "AFTER" 7/29/16

I'm currently running an OEM version of W-7sp1. I'd like to continue to use this after the W-10 cut off date of 7/29/16. However, I'd also like to get a free version of W-10 for futue use. Consequently, I was thinking of doing the following prior to 7/29/16:
1) Removing from my PC my current HDD with W-7sp1 on it and replacing it with a new blank HDD.
2) Installing on this new HDD W-7sp1 from an .iso file I have. I'll be using my current OEM license to activate it.
3) Upgrade this HDD to W-10.
4) Remove this HDD with W-10 installed on it and set it aside for use after 7/29/16.
5) Put back into my PC my original HDD with W-7sp1.

After I have done the above:
a) Will my current HDD with W-7sp1 still be useable? Will I still be able to get W-7 security updates for it?
b) Will my new HDD with W-10 on it be useable after 7/29/16? If it is will I then be able to do a clean install on it (note: my current version is 32bit and by that time I will want to switch to a 64bit version of W-10)?

Thanks for any help that you can give me on this matter.

only thing i can think of may cause you issues right now

Hardware changes

If you made substantial hardware changes to your PC, such as replacing your hard drive or motherboard, Windows might no longer be activated on your PC. For info on how to activate your PC, see the product activation article.

 

Hard drive will not have any effect, motherboard, oh yeah!
