Hello Team,

I am new to Elasticsearch, after reading upgrade documents I came to know that we need to reindex old data,

from below command I can get list of existing index ,  
**curl 'localhost:9200/\_cat/indices?v'**

I can get mappings from below command  
**curl -GET [http://localhost:9200/old\_index/\_mapping?pretty](http://localhost:9200/old_index/_mapping?pretty)**

but i am not sure how to add same mappings and settings to new index which I need to create, can someone help me here,

Regards,  
SAMURAI

You can use the mappings to PUT an index, see [Create index API | Elasticsearch Guide [8.2] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-create-index.html)

If you head to that docs page, [Create index API | Elasticsearch Guide [8.2] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-create-index.html#mappings) is what you want to do to include the mapping.

Hello @warkolm

when i use this  
`curl -X PUT "http://${ES_HOST}:${ES_PORT}/$newindex?pretty"`

it creates the new index  
but when I try to reindex with old it shows success but the values are not correct which means it doenst reindex

```auto
green open old_03 ETKrTJIoRTGdrmxY6lx4nQ 5 1 56220 0 65.8mb 65.8mb
yellow open old_03-new WdNqv-k3Qfi0cklKqQtrBA 5 1 0 0 1.1kb 1.1kb

```

but when I  
` **curl -GET http://localhost:9200/old_index/_mapping?pretty** `

and use the same value to create new index it creates new index and even reindex is working

this is how I am creating new index with mapping value from old index

```auto
curl -X PUT \
http://localhost:9200/old_to_new \
-H 'Content-Type: application/json' \
-d '{"mappings" : {
      "message" : {
        "dynamic_templates" : [

can you please guide what I am doing wrong in reindexing part,

```auto
curl -X POST \
    http://localhost:9200/_reindex \
    -H 'Content-Type: application/json' \
		-d '{
		"source": {
			"index": "old_0"
		},
		"dest": {
			"index": "old_to_new"
		}
	}'

```

Regards,  
Sameer
