Is there any way to rename an index without the need of copying data to another index ?

You can use an alias to do that and point to the old index with it, but to change the original index will require a reindex.

```auto
POST _aliases
{
  "actions": [
    {
      "add": {
        "index": "my-old-name",
        "alias": "my-new-name"
      }
    }
  ]
}

```

does reindexing means we have to copy data to a new index?
