Hello I have a question. I have a RKE 1 cluster and I want to replace the ETCD machines in the pool. What is the best way to do this. Thank you.

good question, I don't know if it's the best way, but I've done it: add new nodes to the etcd cluster and wait until it has reconciled etc. Then remove the old nodes from the cluster. You can always manually promote a new node to leader before deleting a node.

Thank you
