IIRC, Olly previously confirmed that the Xapian database is architecture
independent. I don't think notmuch uses xapian in any weird ways that
should break that.
It should work up to an 1.4.x release of Xapian and 0.29 of
notmuch. Xapian 1.5 (development) and 1.6 (future stable) will drop
support for chert.

It would be wise to make a backup with "notmuch dump" before going much further.
