Is it possible to change the CNI for a rke/rke2/k3s cluster or Rancher launched cluster post-provisioning?

This document (000020904) is provided subject to the disclaimer at the end of this document.


RKE1/RKE2/K3s Clusters
Any cluster provisioned by Rancher


The CNI for a cluster can be specified in the cluster configuration  when launching a Kubernetes cluster via both the CLI and Rancher v2.x. Is it possible to change the CNI after the cluster has been provisioned?


Changing the cluster CNI after the cluster has been provisioned is not supported and care should be taken to set these as required when first configuring the cluster.
