Default [Q] Droid Maxx root upgrade to 4.4

I have a Droid Maxx on verizon. I rooted with RockMyMoto here I have note removed write protection with MotoWPNoMo. Im looking at these instructions Since I am already on 4.2.2 if i just do the MotoWpNoMo can i continue with the instructions or do i need to return to stock first? If i do will pressing full unroot in SuperSu work for this or do i need to flash 4.2.2 again? Any help is appreciated.
