You cannot change the mapping of an indexed document directly. You may

- Ingest again with the correct mapping
- add a new field to receive the converted value using [\_update\_by\_query](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-update-by-query.html#docs-update-by-query-api-source) API
- the most likely best solution would be to [reindex](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-reindex.html#reindex-scripts) into a new index.

Both methods accept a painless script where you can perform your change, check the links I shared.
