This setting is not available until 5.6. Users are technically able to re-index against a previous version. If a user manually migrates their index without this setting and visits the Upgrade Assistant in 5.6, Kibana will still be shown as needing to be re-indexed, however it will fail with "Index .kibana-6 already exists. There may be an unfinished task reindexing to this index, or this index may have not been cleaned up previously."
