How to migrate all services from the current worker node to new nodes in the cluster?

To migrate all services from the current worker node to new nodes in a Kubernetes cluster, you can follow these steps:

1. Add new worker nodes to the cluster.
2. Mark the old node as unschedulable so that no new pods are scheduled on it:

kubectl cordon <old-node-name>

3. Drain the pods from this node to other nodes, including the new ones:

kubectl drain <old-node-name> --ignore-daemonsets --delete-emptydir-data

4. Ensure that all pods are successfully running on the new nodes.
5. After successful migration, you can delete the old node from the cluster:

kubectl delete node <old-node-name>

This way, services will be smoothly transferred to the new worker nodes without downtime.
