Hi Experts,
I know that we can update /create or modify my existing Mappings using SENSE or I can directly achieve this with Mapping API.
My question is do we have any GUI or plugin from where I can update/Delete/Create Mapping for an Index in elasticsearch , Plus I can also change the field type like from string to int etc on the fly. I saw ElasticHQ but in this I can only delete the mapping . Please guide or suggest any other GUI.
Thanks
VG

Hi Vikas,
with a few exceptions [stated here](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-put-mapping.html), the mapping for existing fields cannot be updated. Also, starting [with 2.0 it is no longer possible to delete a type mapping](https://www.elastic.co/blog/great-mapping-refactoring#delete-mappings). To change a mapping you have to create a new index with the new mapping and reindex your data to it. For older versions, this [blog post](https://www.elastic.co/blog/changing-mapping-with-zero-downtime) describes the process. Also note there is work in progress to simplify this reindexing procedure using a dedicated API for this, see this [Github issue](https://github.com/elastic/elasticsearch/issues/15201) for details.

Thanks for the response Chris,
I like Alias Idea , but since i am new so I followed the instruction as per blog the only challenge for me is to copy old index document into new index .Till now what I have done is
1. I have created alias for my existing Index and then create a new index with new name and mapping and assigned the same alias name to it.e.g
> ```
> POST /_aliases> {
> "actions": [
> { "remove": {
> "alias": "vikas_alias",
> "index": "corr"
> }},
> { "add": {
> "alias": "vikas_alias",
> "index": "vikas"
> }}
> ]
>
> ```
Here **corr** is my old index and **vikas** is my new index.
1. After doing all above I can see following after firing **GET /\_cat/indices/?v**

You can use something like Logstash to do that, [https://gist.github.com/markwalkom/8a7201e3f6ea4354ae06](https://gist.github.com/markwalkom/8a7201e3f6ea4354ae06)
