I have a K8S cluster versioned 1.11.
I have calico installed as cni plugin. I need to replace it with flannel.
I found guides online how to migrate from flannel to calico but not the other way around.
Down any one have a tip/idea how to get by this?
Is it even possible migrating from Calico to flannel?
Thanks
Migrating a cluster from Flannel to Calico is feasible but migration from Calico to Flannel is not supported.
This is mentioned in the documentation provided by Calico:
Rollback: Migration from Calico to flannel is not supported.
