Hi Team,

we are using 180 days retention for all the data in our Elastic cluster. Now we have some transforms where we are using the transforms retention\_policy to keep the data for 180 days. Now we wanted to remove the retention policy from transform and create a ILM policy to handle the data in multiple phases like hot, warm, cold and delete. Could you please suggest us if we can do that.

Thanks in Advance.

As outlined in the documentation [it is not recommended to use ILM with transform destination indices](https://www.elastic.co/guide/en/elasticsearch/reference/current/transform-limitations.html#transform-ilm-destination) as it can cause duplicates.
