not a support question

Here is what I did
1. stop cassandra service with: service dse stop
2. open up /etc/dse/cassandra/cassandra.yaml and change the 'initial_token'
3. restart cassandra with: service dse start
But I don't see the change takes effect, nodetool still shows the old token. I guess there must be some steps I missed, especially after reading http://wiki.apache.org/cassandra/FAQ#clustername_mismatch
Thanks!
Once a server has been run once, the initial_token is no longer being used (it's only used for the initial determination of the servers token). Please check http://wiki.apache.org/cassandra/Operations#Token_selection on how to change token assignments. The easiest way to manage your nodes is through OpsCenter Enterprise Edition http://www.datastax.com/docs/opscenter/online_help/cluster/node_actions#rebalance-cluster.
Thanks,

What version of Cassandra are you using? You will need at least 0.8.2 for the OpsCenter functionality to work.
txie,
The opscenter agent must be properly installed and configured [1] on each node in order to do a move.

Cool, glad it worked out. Thanks for letting us know.
