Is a campag 11 speed cassette a straight swap for campag 10 speed?

or does it mean a different freehub body or even a new wheel?

I'm thinking of putting something 'nicer' than Veloce Race Triple, like 11-speed Athena on the best frame; Genesis Equilibrium 853.

Straight swap on the wheel.

It's the shifting that'll need looking at.

Yep, hence I'll be changing the shifters....
