Hi Juan, tnx for the answer i saw the above while googling as well, but figured it might have changed in the newer versions, guess not. thanks again for responding

I won't say is not possible... it's something really tricky and very dependent on the CNI and the use case; that's why no Kubernetes distro supports it (for example is not either supported on OpenShift). It's way simpler to have a second cluster with the new CIDR and migrate workloads there. Sorry :(
