No 1.0 cluster is required to restore 1.0 directory structure to a 1.1
cluster and have the tables be migrated by Cassandra. The 1.1 node
should look at the 1.0 directory structure you just restored and
migrate it automagically.

This is a compelling reason to bulk load. My commentary merely points
out that if you *aren't* changing cluster size/topology, Cassandra 1.1
should be migrating the sstables for you. :)
