Hi, due to internal infrastructure changes, we have to replace all nodes with new nodes. All the existing nodes are running Cassandra Community version 2.0.9. I was thinking may be this is also an opportunity for us to upgrade to Cassandra Community version 2.1.14. I hope I am not asking a crazy question: But can I replace a 2.0.9 node with a 2.1.14 node in the cluster, i.e. can 2.0.9 nodes and 2.1.14 nodes work peacefully together in a cluster if I replace 2.0.9 nodes with 2.1.14 nodes one by one?
Thanks. George.
