# ILM and Curator!
<warning>
  Curator will not act on any index associated with an ILM policy without setting `allow_ilm_indices` to `true`.
</warning>

Curator and ILM *can* coexist. However, to prevent Curator from accidentally interfering, or colliding with ILM policies, any index associated with an ILM policy name is excluded by default. This is true whether you have a Basic license or not, or whether the ILM policy is enabled or not.
Curator can be configured to work with ILM-enabled indices by setting the [`allow_ilm_indices`](https://www.elastic.co/elastic/docs-builder/docs/2423/reference/elasticsearch/curator/option_allow_ilm) option to `true` for any action.
