 Now that you’ve created a component template, you need to create an index template to apply the changes to the correct data stream. The easiest way to do this is to duplicate and modify the integration’s existing index template.

-- If you duplicate an index template, do not change or remove any managed properties. This may result in problems when upgrading. Cloning the index template of an integration package involves some risk as any changes made to the original index template are not propagated to the cloned version when you upgrade versions.
