Mountain lion MDC Mavericks client?

Starbytes's picture

We've got an Xsan 10.8 running and all the clients are also running Mountain Lion.
Is it possible to update the clients to Mavericks 10.9 without updating the MDC's?

I know mavericks runs Xsan 3.1 and ML 3.0 and Apple says "The Xsan and OS X versions running on MDCs must always be the same or later versions than those which are running on the Xsan clients."

But still.... :)
