Xapian (and notmuch) will continue using the 1.2 era "chert" backend for
existing databases. This is what I've been doing for some time now,
using a chert backend with xapian 1.3. To force an upgrade to glass
would require dump, move .notmuch out of the way, notmuch new, and
restore. That should also work, since the test suite uses the glass
backend, but I'm not sure if it's worth the trouble at this point. I
know that the Xapian team is still doing performance tuning on the glass
backend.

all the best
