How to create new index with old index mapping and settings

Elastic Stack Elasticsearch
1

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

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

Hello @warkolm ,

curl -X PUT "localhost:9200/my-index-000001?pretty"

I am sorry for my silly question sine I am new to ES need some help here.

If you head to that docs page, Create index API | Elasticsearch Guide [8.2] | Elastic 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

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

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

    -H 'Content-Type: application/json' \
		-d '{
		"source": {
			"index": "old_0"
		},
		"dest": {
			"index": "old_to_new"
		}
	}'
