Snapshot from higher to lower version

Elastic Stack Elasticsearch
1

Hi,
Due to some unavoidable situation, we have snapshot and restore from 6.3 to 5.6.6 version of elasticsearch.
Is that possible?

No, indices from newer versions of Elasticsearch can not be read by older versions. You may however be able to restore it in a 6.3 cluster and reindex from remote.

If I understand correctly,
I have ES6.3 on host1
I have ES5.6 on host2 -- Running cluster
So, I will make reindex.remote.whitelist: host1:9200 in elasticsearch.yml on Host2 (ES5.6)
And then KIbana5.6 will show the data from ES6.3?
IS that correct?

BR,
Sunil.
