Hi, I am Dave, I will help you with this.
Windows is very adaptable to new hardware and usually you can use the current installation and on the first boot you will see the 'Getting Things Ready' screen while Windows installs the necessary drivers for the new hardware.
But there is no guarantee that Windows will be able to adapt successfully to the new hardware, so before you swap in the new hardware and try to boot up Windows, you should backup all your personal files to a safe location in case you do need to clean install Windows from a bootable USB
