Cracking open a Magnifica S Smart, anyone done a teardown?

is the brew group on these the same as the older magnifica or did they change the design? i have spare orings from my old one wondering if they'll fit

same brew group basically, the orings are interchangeable. The gearbox changed but the wet end where the brew group connects is the same on the newer models
