From Elasticsearch Synthetic Source to Opensearch Derived Source

OpenSearch
1

Versions 3.2.0

Describe the issue: Is there a way we can do in-place upgrade from Elasticsearch Synthetic Source to Opensearch’s Derived Source because conceptually both are doing the same thing of not storing _source field.

Context: I want to move away from elasticsearch but I have indices that are synthetic which I don’t want to migrate or reindex.

Configuration: NA

Relevant Logs or Screenshots: NA

@adityateltia I don’t believe this is possible, although they seem to be doing the same thing what happens under the hood is actually quite different. One of the way you can migrate is using remote reindex. I test locally in place upgrade and snapshot approach, and came across errors with UUID and data path.
