I'd like to upgrade from 1.1.6 to 1.2.1, one big feature in 1.2 is

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
Is there other doc about this upgrade path?
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).
