Redistribute pods across AKS node-pools

Question

Is there a safe way to restart a node pool to force/induce kubernetes scheduler to redistribute pods across node-pools?

Context:
I recently upgraded the SKU of my system node-pool and I would like all/most of the system pods running on user node-pools to be re-allocated there. I have taints and tolerations correctly set on nodes and pods to induce this behaviour.

Thanks!

You should be able to do this by Draining and Uncordoning Nodes.

Drain the nodes: kubectl drain <node-names> --ignore-daemonsets --delete-emptydir-data, using a space-separated list of node names.

Stop the Node Pool: az aks nodepool stop --resource-group <resource-group> --cluster-name <cluster-name> --nodepool-name <nodepool-name>

Start the Node Pool: az aks nodepool start --resource-group <resource-group> --cluster-name <cluster-name> --nodepool-name <nodepool-name>

Uncordon the Node Pool: kubectl uncordon <node-name>

Hope this helps! Let me know if you have issues or need further assistance.
