Move bath lav stubout

[Sampep]

I need to move my bathroom lav stubout about 6” to the left of where it’s at now. I want to minimize how much drywall I need to cut out and repair.

Here’s how it looks (got a picture when it was last remodeled):

I want to be code complaint for California. Here are a couple ideas I had. I’m not sure if I should cut a new path for the vent or leave the old one there. I assume long sweeps are required below the stubout San tee, but 90s are ok for above for the vent?

Cut out a section incl the tee. Then do a tee rotated into the direction over and add a long sweep 90 or l.s. street 90 for the stub out. Use no hub couplings to resect.
No need to mess with any of your illustrations.
