Hi @elk3,

In elasticsearch, snapshots can't be read by older versions. You can restored snapshot to version 6.7.2 and above only.

You can reindex your indices in older version if you want.

Hi @elk3,

You can use logstash to read the data from elasticsearch-6.7.2 host and send it to elasticsearch-6.7.1 host. Like in logstash input plugin configure your elasticsearch-6.7.2 host and in output plugin configure your elasticsearch-6.7.1 host.

I found a blog for the same. Please refer below link for reindex elasticsearch with logstash.
This is for older version but you can get idea in details that how it works.
