Christian, I have been planning to migrate my cluster from random to murmur3 in a similar manner. I intend to use pycassa to read and then write to the newer cluster. My only concern would be ensuring the consistency of already migrated data as the cluster ( with random ) would be constantly serving the production traffic. I was able to do this on a non prod cluster, but production is a different game.
I would also like to hear more about this, especially if someone was able to successfully do this.
