Opensearch Migration

I have Elasticsearch running on 7.10.2 basic license. I want to migrate to opensearch. What are the options do i have to migrate the elasticsearch data? Is that true only Elasticsearch-oss eligible for rolling upgrade not basic licensed ones? If so, what should I do to migrate the data?

Can someone update here please?

You should be able to migrate your data from ES 7.10.2 to OpenSearch 1.x using snapshot and restore. You need to configure a snapshot repo on your current cluster, take the snapshot , point the same shared repo to OpenSearch cluster when restoring, and finally restore the snapshot. Checkout this documentation on how to configure and run snapshot restore - Take and restore snapshots - OpenSearch documentation
