Boot on one SSD, system C: on another, how to merge safely?

[Arctree]

Hi
Advice sought:

If you look at the pic enclosed, my boot sector is on Samsung SSD EVO
But my System C is on OCZ Agility.

The problem as I see it.
My boot sector is on the drive I want to keep (Samsung EVO 870 SSD (GPT) disk)
but C: is on a an old SSD (OCZ Agility SSD SYSTEM PRIMARY (C

Can I just clone C: to the empty space on D: and expect it to then boot from D having disconnected
OCZ AGILITY ? Or will it go horribly wrong?

At what point would D become C ? would the system sense it and just change it? Or would I need to do that somehow?

Regards
Sean

Hi Ubuysa (and anyone else)
Almost a solution and but I need to move C: to D: when D: already has the boot sector on.
This looks very promising and if I think about it and print it off it should get me there, unless anyone else has any thoughts on the potential for W10 to not do what I tell it.

TBH In your position I would just reinstall.
