Hi all,

Is any way to rollover for "Transform" indices? If I use ILM policy, I'm getting error: "**illegal\_argument\_exception: index.lifecycle.rollover\_alias [test-summary] does not point to index [test-summary]**".  
Template setting:

```auto
{
  "index": {
    "lifecycle": {
      "name": "test-summary",
      "rollover_alias": "test-summary"
    },
    "number_of_replicas": "1",
    "refresh_interval": "5s"
  }
}

```

In ILM is using only rollover on "Hot Phase". Template was created before "Transform" execution (and index\pattern creation).

Any help would be appreciated.

Thank you!

Using ILM with transform [can cause duplicates to be created](https://www.elastic.co/guide/en/elasticsearch/reference/8.4/transform-limitations.html#transform-ilm-destination) and is not recommended/supported.
