I've booked a 2h10m I-I transfer from T2A/C to T1. No checked baggage, should have onward boarding pass already. It's on the same ticket so I should be protected if everything goes very wrong.

After clearing transfer security, does the 'airside' shuttle mentioned in the first post ["Take the Aéroports de Paris shuttle bus (within customs zone) situated close to the Transfer desk"] still exist? I can't find many recent references. If it does, is it the green bus as shown here?

I'm perfectly capable of passing immigration twice and taking the CDGVAL but it would be nice if it can be avoided. I think I'd still probably be okay on time unless my first flight is significantly delayed? I can walk fast.
