I think needs to be clear in the doc that the migration from kubenet to CNI overlay can't change pod-cird

Hello all,

we tried my cx and myself to move from kubenet to CNI Overlay and change the --pod-cidr but it does not work. After that checked with a colleague from engineering team and he told me not possible.

**https://learn.microsoft.com/en-us/azure/aks/upgrade-aks-ipam-and-dataplane#kubenet-cluster-upgrade

Since the cluster is already using a private CIDR for pods which doesn't overlap with the VNet IP space, you don't need to specify the --pod-cidr parameter and the Pod CIDR will remain the same if the parameter is not used.**

It could be possible to re-write the paragraph above as I think it leave the option to use the --pod-cidr and the change of it doing the migration and it seems not possible please?.

Thank you
