Warning -

Due to a change in the SCC, on OpenShift clusters running version 6.2.12 or earlier upgrading to version 6.2.18 or later, where node:1 is not the master node, the upgrade might get stuck.

For more detail and steps to prevent this issue, see upgrade a Redis Enterprise cluster (REC).

Note:
On clusters with more than 9 REC nodes, a Kubernetes upgrade can render the Redis cluster unresponsive in some cases. A fix is available in the 6.4.2-5 release. Upgrade your Redis cluster to 6.4.2-5 before upgrading your Kubernetes cluster.
