Need help figuring out next steps

I've been out of the loop lately but I've had my note 3 for a while, originally it was on a Samsung based kitkat rom, after that I flashed a Cyanogenmod based lollipop rom.
Currently I've been using the Cyangonmod based rom for a few months and I want to switch to a Samsung based lollipop rom but I'm confused about my next steps? What should I be doing, is there anything i need to do to prepare before flashing the samsung based rom in recovery.
