You must upgrade the node pool under the Worker nodes of the Workload clusters created in VMware Telco Cloud Automation 1.7.

Upgrade all the node pools under workload clusters before upgrading the Kubernetes cluster. If not upgraded, you cannot edit the node pools or instantiate CNF. Consider the following points before upgrading the node pool:
  • Node pool upgrade is a one time operation required when upgrading from VMware Telco Cloud Automation 1.7 to VMware Telco Cloud Automation 1.8.
  • There could be an application down-time during the upgrade as VMs may reboot depending on the customization.
  • You can retry the failed node pool upgrade operations after making the required changes.
