You can follow these steps for your version also . http://www.datastax.com/docs/1.0/install/upgrading
If you will keep the data directory same in Cassandra.yaml, data will be picked in new node.

Currently I have two Cassandra nodes running in ring. I have installed Cassandra on following location; /root/apache-cassandra-0.8.1 Now my questions are; 1. How we upgrade (Step by Step version like 0.8.1 to 0.8.5, then 0.8.5 to 1.0.0..........to 1.1.0) 2. Once I take snapshot, is it have full data or only one node data? 3. Once I download apache-cassandra-0.8.5-bin.tar.gz then after untar, What Can I do? I only move few folder from previous version directory to new version directory or move all directories and files. 4. After moving data is there any command required ? Thanks & Regards Adeel Akbar
