Brake rotors, CPO
This is two questions actually. I want to know What Porsche would allow as acceptable for a CPO car in terms of rotor condition. The car in question has a small, maybe 2-3 mm lip on the rotors. Is that OK? My personal preference would be zero ip. The car has 54K miles on it . Second question is, how difficult is it to change rotors? Any special tools needed? Thanks.

On the 986/996 platform, the amount of wear before replacing the rotor is 2mm, which means 1mm of lip on each side. If the rotors you see have 2-3mm of lip it sounds like they might be past time to be replaced.
Rotors are pretty easy to replace.

You can measure total rotor's thickness. If less then 2mm total from original then "officially" you need to replace. There are tons of replacement rotors/pads: drilled and slotted at your preference. It takes about 30 min per side to replace or slightly more if holding screw is stuck. Very easy.

Have the dealer measure the rotor thickness and document it. Technically it’s 2mm from original thickness. As a diy, extremely easy. Look at pelicanparts.com for a diy or several others on the web. Confirm which calipers are you have as here are many variants out there.

With that said, I buy ATE rotors at $85/piece.
If it's your first time changing rotors, plan for 4-6 hours.
It will take you longer than 30min per side. I'm fairly efficient and have all the right tools and have done this multiple times. It probably takes me 3 hours including pad change and cleanup meaning putting all my tools back, throwing out the boxes etc..
Depending on the your location a "punch' screw driver is helpful for removing the the rotor retaining screw and a heavy rubber mallet if your rotors haven't been off in 50k miles.
