We deployed k8ssandra-operator into our EKS cluster and installed cassandra 4.0.3. We want to upgrade the cassandra version while the system is live. Can you describe the process, point to documentation, or just comment on the right way to do that?
Thanks.
Hi, you just need to change the Cassandra version in your K8ssandraCluster manifest and apply it. The operator will then take care of the rolling upgrade, including the upgradesstables operation.
