Ah. I was going by the upgrade recommendations in the NEWS.txt file in the cassandra source tree, which didn't make mention of that version (1.0.11) whatsoever. I didn't see any show-stoppers that would have prevented me from going straight from 1.0.9 to 1.2.x.

Looks like a multi-step upgrade is the way I'll be proceeding. Thanks for the insight, everyone.

Because this fix in 1.0.11:
* fix 1.0.x node join to mixed version cluster, other nodes >= 1.1 
(CASSANDRA-4195)
