You're lucky, according to Elasticsearch documentation:

A snapshot of an index created in 2.x can be restored to 5.x.

Also, Elasticsearch has:

repository-s3 for S3 repository support

,which should be very useful in your case, I assuem.

The full guide how to do that is there. I will try to some of them:

Before any snapshot or restore operation can be performed, a snapshot repository should be registered in Elasticsearch. The repository settings are repository-type specific. See below for details.

PUT /_snapshot/my_backup
{
  "type": "fs",
  "settings": {
        ... repository specific settings ...
  }
}

After several others steps, like verifying snapshot, you could restore it:

A snapshot can be restored using the following command:

POST /_snapshot/my_backup/snapshot_1/_restore

Is there a difference between Restoring Data & Migration? – Inherited Geek Feb 07 '17 at 13:23
in which terms? – Mysterion Feb 07 '17 at 13:26
I want to copy my data from ES 2.3 to ES 5.1 now is this process migration or restoring or do they mean the same thing? – Inherited Geek Feb 07 '17 at 14:00
if you made a snapshot, it's a question of restoring data – Mysterion Feb 07 '17 at 14:33
