Copy data to new index and change data type

Elastic Stack Elasticsearch
1

I need to change data types of two of my fields.

  1. From string to object
  2. From Nested (array) to object.

I understand that this cannot be changed within the same index and I would have to use _REINDEX.

I am been trying to do this but been largely unsuccessfull.

Example:

Below are the current fields:

"role": "Full",
"access": [
            {
              "client": "Full"
            }
 ]

New fields:

"role": {
            "env1": "Full",
            "env2": "Full",
            "env3": "Full"
          },
"access": {
            "env1": [
              {
                "client": "Full"
              }
            ],
            "env2": [
              {
                "client": "Full"
              }
            ],
            "env3": [
              {
                "client": "Full"
              }
            ]
}

I understand that we use ingest node feature but it doesn't seem to work with objects. Please help?
