HI There,

I have a MP 4.1 2009 flashed to 5.1 and upgraded of a single processor and I have bought just the tray of another MP 4.1 but dual processor (it hasn't been flashed to 5.1). Currently I'm running Mojave and so far has been working great. I wonder what is the best way I can swap the tray, Do I need to reinstall all the OS again? any advice how should be the best way to do it?
Thanks
