It does not seem to be possible to change the CNI after the cluster has been installed: Not sure if I can do it manually somehow still like for example deleting the Weave pods and the Daemonsets.
I have made the observation that setting
plugin: none
in RKE does not uninstall the plugin. But you can use a migration tool or uninstall it manually and RKE will not manage the network plugin any more
I have migrated from flannel to calico sucessfully this way
in general it is a bad idea to change the CNI after the cluster is up. I would recommend against it unless you either like fixing broken things, or know what you’re doing.
