# KubeZero - Cluster upgrade
`(No, really, you MUST read this before you upgrade)`
Ensure your Kube context points to the correct cluster !
1. Review CFN config for controller and workers, no mandatory changes during this release though
2. Upgrade CFN stacks for the control plane *ONLY* !
Updating the workers CFN stacks would trigger rolling updates right away !
3. Trigger cluster upgrade:
`./admin/upgrade_cluster.sh <path to the argocd app kubezero yaml for THIS cluster>`
4. Review the kubezero-config and if all looks good commit the ArgoApp resouce for Kubezero via regular git
git add / commit / push `<cluster/env/kubezero/application.yaml>`
5. Reboot controller(s) one by one
Wait each time for controller to join and all pods running.
Might take a while ...
6. Upgrade CFN stacks for the workers.
This in turn will trigger automated worker updates by evicting pods and launching new workers in a rolling fashion.
Grab a coffee and keep an eye on the cluster to be safe ...
Depending on your cluster size it might take a while to roll over all workers!
7. Re-enable ArgoCD by hitting <return> on the still waiting upgrade script
8. Head to the ArgoCD UI and sync all KubeZero apps to verify all are synced successfully.
