Hello, I have a production work load running on Apache Cassandra 2.1.0 version. And I want to upgrade my Cassandra version to 3.11.6. There are total 7 nodes in one cluster.
I have successfully upgraded Cassandra version with data to 2.1.9 version with dump and restore of data approach. Now, I want to upgrade to Cassandra 3.11.6 version, can I directly upgrade to 3.11.6? Or should I upgrade Cassandra to 3.0.5 and later to 3.11.6?
