Default [Q] Upgrade PA 3.1 to 4.43

Hey, does anyone know what are the required steps in order to upgrade from Paranoid Android 3.10 on the Nexus 4 to Paranoid Android 4.43?
Is there a need to update the radio/kernel/recovery? (My recovery is Team Win v2.4.1.0)
Haven't dealt with this for about two years, totally forgot.

Thanks!
