Windows 10: Windows 11 clean install from HDD to SSD

I'm trying to completely wipe everything off my computer and reinstall Windows 11 from scratch. I built my computer around two years ago and installed the Windows 11 OS onto a 2TB HDD but now have a 2TB SSD and want to install it there and swap out the 2TB HDD for an 8TB HDD. I have already gone through the process of backing up everything I want onto a separate flash drive. I also still have my Windows 11 install USB with the product key from when I originally installed it. My questions are:First, can I reuse my product key automatically or is there some process I have to go through to deacti

2. I have HDD in my system and a SSD slot ( Sata M.2). I am planning to use both. In order to boot windows from the SSD, do I need to delete the previous windows in the HDD?

Add to other given instructions:

Disconnect old HDD before doing clean install to SSD. If you don't do that it will create dual boot system and all boot information is located to that old HDD.

When new OS is installed to SSD you can reconnect old HDD, but go to BIOS and make sure that SSD is set to first boot device.
