Issue while updating AKS cluster with deprecated control and data plane

Sylvain Barbot 21 Reputation points

I have an aks cluster with :

  • k8s 1.19.13 on the controle plane
  • k8s 1.17.13 on the data plane

I need to update the controle plane as <1.20 will no longer be supported, but I can't:

  • If I update the controle plane, it ask me to upgrade the dataplane first, as only 2 minor version bellow can be supported (1.17+2<1.20).
  • So I try to update the data plane first, but I can't as 1.19 is no longer supported, it prevent me from upgrading the nodes...

I'm stuck in this situation and don't know how to upgrade neither the control plane or data plane...

    Going with the cli, I was able to upgrade my dev cluster, I'm currently doing my production cluster but I suppose it will work too :-)
    Thank you for the support.
