# Copy or move an index

> Copies or moves (renames) an index within the same Algolia application.

**Required ACL:** `addObject`

Notes:

* Existing destination indices are overwritten, except for their analytics data.
* If the destination index doesn't exist yet, it's created.
* This operation is resource-intensive.

**Copy**

* If the source index doesn't exist, copying creates a new index with 0 records and default settings.
* API keys from the source index are merged with the existing keys in the destination index.
* You can't copy the `enableReRanking`, `mode`, and `replicas` settings.
* You can't copy to a destination index that already has replicas.
* Be aware of the [size limits](https://www.algolia.com/doc/guides/scaling/algolia-service-limits/#application-record-and-index-limits).
* For more information, see [Copy indices](https://www.algolia.com/doc/guides/sending-and-managing-data/manage-indices-and-apps/manage-indices/how-to/copy-indices).

**Move**

* If the source index doesn't exist, moving is ignored without returning an error.
* When moving an index, the analytics data keeps its original name, and a new set of analytics data is started for the new name.
  To access the original analytics in the dashboard, create an index with the original name.
* If the destination index has replicas, moving will overwrite the existing index and copy the data to the replica indices.
* For more information, see [Move indices](https://www.algolia.com/doc/guides/sending-and-managing-data/manage-indices-and-apps/manage-indices/how-to/move-indices).

This operation is subject to [indexing rate limits](https://support.algolia.com/hc/articles/4406975251089-Is-there-a-rate-limit-for-indexing-on-Algolia).
