hi, I am using Elasticsearch 6.2.4, and I migrate some historical data from old cluster to a new one.The historical data would not be used recently,so I set box\_type to warm. But after I migrate the data to the new cluster,I find box\_type had been changed to hot. And I do not know why this happened. Hoping for your help, thank you. ---

`box_type` is not a native Elasticsearch structure, but likely a node attribute. It's not possible to tell why you're seeing a particular node attribute show up without some more details on your configuration. ---
