I'm not sure that'll work with that many version moves in the middle,
upgrades are to my knowledge only tested between specific steps, namely
from 1.2.9 to the latest 2.0.x

Cassandra 2.0.x restrictions¶

After downloading DataStax Community <>,
upgrade to Cassandra directly from Cassandra 1.2.9 or later. Cassandra 2.0
is not network- or SSTable-compatible with versions older than 1.2.9. If
your version of Cassandra is earlier than 1.2.9 and you want to
perform a rolling
first upgrade the entire cluster to 1.2.9, and then to Cassandra 2.0.
Cassandra 2.1.x restrictions¶

Upgrade to Cassandra 2.1 from Cassandra 2.0.7 or later.

Cassandra 2.1 is not compatible with Cassandra 1.x SSTables. First upgrade
the nodes to Cassandra 2.0.7 or later, start the cluster, upgrade the
SSTables, stop the cluster, and then upgrade to Cassandra 2.1.
