Question New build. Reinstalling gaming clients questions.

[balloonshark]

I just built a new PC and I'll be using my HDD's from my last build where I had my clients and games installed. Should I install my clients on my new NVMe drive or reinstall them on the HDD's? If so what's the best way to do it since there is no way to uninstall the clients short of reinstalling in the old location and uninstalling them. Or would I just delete everything in the folder/s except the games themselves?

Edit: I got steam done and it was easy. I just deleted everything but the steamapps folder on D: then installed steam on c: and in the options setup the old steam folder on D: as the downloads folder.
