Is it possible to migrate Elasticsearch from 8.9 to any Opensearch version?

**Thing we have rule-out :**

- Re-index is not an option as it takes long time.
- Snapshot and Restore fails with UUID error.
- Dual Writes is possible but cluster is only one.

We are looking for how to replace Elasticsearch in to Opensearch in existing cluster itself.
