# Clone Index

Clones an existing index.

Indices can only be cloned if they meet the following requirements:

* The target index must not exist.
* The source index must have the same number of primary shards as the target index.
* The node handling the clone process must have sufficient free disk space to accommodate a second copy of the existing index.
