Hi,
I have 7 node cluster,
master nodes - 3
hot nodes -2
warm nodes-2
An application creates daily indexes and sends indexes to a cluster.
I want to use hot warm architecture for this cluster.
I want to know how to use the ILM policy without re-indexing(changing the index name) to move data from the hot phase to the warm phase...
index pattern ex: abc-{year}-{month}-{day}
Using elasticseach 7.10.1
Thank You!

Hi,
First, you need to define your node's roles, i.e., hot, warm and cold.
Then you just [configure your lifecycle policy](https://www.elastic.co/guide/en/elasticsearch/reference/current/set-up-lifecycle-policy.html#ilm-create-policy) and enable your phases. They'll automaticly move to the next phase when the conditions are met.
I suggest you read [this blog](https://www.elastic.co/blog/implementing-hot-warm-cold-in-elasticsearch-with-index-lifecycle-management). I'm sure it'll answer most of your questions.

Thank You immediate response.
Before I configure the hot-warm architecture, warm nodes(now) were configured as data nodes. Then how do I configure warm nodes?
node.role = [data\_warm, data] or node.role = [warm\_data] ?
Thank you!

According to [docs](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-node.html#data-node):
> In a multi-tier deployment architecture, you use specialised data roles to assign data nodes to specific tiers: `data_content` , `data_hot` , `data_warm` , or `data_cold` . A node can belong to multiple tiers, **but a node that has one of the specialised data roles cannot have the generic `data` role.**
So you should use `node.role = [warm_data] `

I referred above resources. But I was unable to find a method to move data in the warm phase without changing the index name.
I want to know how to move hot data to warm data nodes and will every rollover action change the index name after moving to the warm phase?
Can I move data from hot to warm by using index.lifecycle.indexing\_complete is set to true?
Thank You!
