Do you have any index templates that match the new index name (reporting-2017.08.12-reindexed)? There's a bug that will be fixed in 5.6 that causes index templates to be applied to the new index (https://github.com/elastic/elasticsearch/pull/25380).

In the meantime, you could make sure that the new index has a name that would not match the index template.
