Changing node.attr.data from hot to warm

Hello,

Just wondering what's the expected behaviour when we change the node.attr.data attribute from hot to warm in elasticsearch.yml and restart elasticsearch. As I'm preparing to add some new warm nodes to our cluster, I tried that on our QA and nothing seems to happen. How can I move all indices that are still in hot phase on the node that is warm to hot nodes?

Grtz
