how can I upgrade to 1.2.1 then breaking the token to take advantage
of this feature? I went through this doc but it does not say how to
change the num_token
http://www.datastax.com/docs/1.2/install/upgrading
Is there other doc about this upgrade path?
Thanks,

I think for each node you need to change the num_token option in
conf/cassandra.yaml (this only split the current range into num_token
parts) and run the bin/cassandra-shuffle command (this spread it all
over the ring).
