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.

​
Parameters

ParameterDescription
IndexName of the source index to clone.
SettingsConfiguration options for the target index.
Target IndexName of the target index to create.

Index names must meet the following criteria:

- Lowercase only
- Cannot include , /, *, ?, ”, <, >, |, ’ ’ (space character), , (comma), #
- Indices prior to 7.0 could contain a colon (:), but that’s been deprecated and won’t be supported in 7.0+
- Cannot start with -, _, +
- Cannot be . or ..
- Cannot be longer than 255 bytes (note it is bytes, so multi-byte characters will count towards the 255 limit faster)
- Names starting with . are deprecated, except for hidden indices and internal indices managed by plugins.
