Thanks for the link Rob, but I did try earlier to copy the SSTables over and then to refresh them, but this is a brand new cluster and the error I got back indicated that the keyspace didn't exist, and then figured I needed to copy everything over in the data directory.

What would be the best way to move the data and utilize it on the new cluster. I have looked at snapshot and also just copying the entire tree from the old cluster to the new cluster. Not sure what the best practice would be. I'm testing that process now in preparation for moving the current data (production) to the new larger ring (systems are bigger and more memory) and decommission the older ring (smaller systems, less memory). http://www.palominodb.com/blog/2012/09/25/bulk-loading-options-cassandra In your case, I would just copy all sstables to all target nodes and run cleanup. =Rob
