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.

I'm sure there's a way to do this more efficiently, like replacing the nodes and restoring an ETCD backup, but I didn't want to do that.
