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.

how reindex to older version

[harshbajaj16 (Harsh Bajaj)]

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.
