Hi,

As title says, is it possible to Reindex to change the name of multiple fields?  
Instruction shown [here](https://www.elastic.co/guide/en/elasticsearch/reference/5.2/docs-reindex.html#docs-reindex-change-name) is only for single field.

Thanks!

Can you show me a simple example?  
I tried to nest script field but it gives me a syntax error

Just the script portion:

```auto
"script": {
  "inline": "ctx._source['newfield1'] = ctx._source.remove('oldfield1'); ctx._source['newfield2'] = ctx._source.remove('oldfield2');"
}

```
