To add, we deployed kubernetes 1.24.4 using rke 1.3.15, and then all our applications. We need to change the current cluster_cidr and service_cluster_ip_range to new subnets, but would like to avoid tearing down the cluster and re-deploying our applications and their components. Does any one know how best to do this, if it is possible. Or point me to any documentations that might help us. Thanks in advance.

No, doing that is not really supported by Kubernetes. You basically need to delete all the nodes, pods, and services to readdress. You might as well just rebuild the cluster.
