[Q] Quick Q on Reverting from Rooted 5.0.1 to Nandroid 4.4.4 topic

I've tried searching a bit and maybe not thoroughly so please forgive me if this was answered already. I upgraded from rooted 4.4.4 to rooted 5.0.1. I have latest TWRP recovery and I have made nandroid backup before doing the upgrade. I was thinking to just go to TWRP and run restore, but I wanted to make sure I am doing things correctly and notting missing some crucial steps.

I appreciate your input on this.
