Migrate data to existing index in sanpshot approch in Elastic Search

Elastic Stack Elasticsearch

Hi,
I want to migrate the data from one elasticsearch cluster to another using snapshot from a remote server.
Is it possible to restore the old data to new cluster, the approch we are thinking is ot:-

  1. change configuiration to new cluser in place of old cluster for new logs
  2. take snapshot from old cluser
  3. restore it on the new cluster

Please suggest if this can we be done with elasticsearch, snapshot approch.

Thanks with Regards,
Rahul Gupta

It is not entirely clear to me what you are asking for. Snapshot and restore moves complete indices and these can not be merged into existing ones. The versions used in the two clusters must also be compatible.

Could you please provide some additional details around the process you are considering?
