Cassandra Upgrade from 0.8.1
Dear Guys,
Thank you so much for your reply.
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

You can follow these steps for your version also .

If you will keep the data directory same in Cassandra.yaml, data will be picked in new node.
