I have corrupted a set of indexes, `nginx-*` , by trying to modify the type of a particular field with the PUT mapping API. I get this error in Kibana settings/indices page:

```
A field is defined as several types (string, integer, etc) across the indices that match this pattern...

```

As this is not just one index, closer to 30, what is the best way to resolve this issue? I understand I may need to reindex

```
Correcting this issue will require reindexing your data.

```

Is there an easy way to reindex a glob of indices? eg, I want to reindex nginx-2015.11.15 to nginx-v2-2015.11.15 , for all dates. Or is my only real option to script this in python or bash or something? Does anyone have a clear example of how exactly to reindex? To me this article here is missing something critical -- [https://www.elastic.co/guide/en/elasticsearch/guide/current/reindex.html](https://www.elastic.co/guide/en/elasticsearch/guide/current/reindex.html) -- the only example it gives is `GET /old_index/_search?search_type=scan&scroll=1m`.. so this is how you get the old data, but how exactly do you insert that into `new_index` ?

You can use simple bash script (to iterate over indexes) and logstash to transfer data from one index to another. Look at [Reindex using bulk api](https://discuss.elastic.co/t/reindex-using-bulk-api/31713/2)
