How to move data from ES 5.0 on one server to ES 6.1 on different server?

Hi ,

can someone please guide on moving data from Elastic search 5.0 version on one server to different server with higher elastic search version 6.1/6.2.

Thanks,

Elasticsearch can usually be upgraded using a Rolling upgrade process so upgrading does not interrupt service. However, you might need to Reindex to upgrade indices created in older versions.
