Restore-elastic-search-snapshot-from-2-3-0-to-5-6-0

Thanks, Abdon
I am able to resolve it.
I was using

path.repo: ["C:/backup_elasticsearch_2_3_0"]

but when I used

path.repo: ["C:\\backup_elasticsearch_2_3_0"]

It is working fine.

But I noticed that indices is restored in elasticsearch 5.6.0 with some dummy name instead of "event-YYYY.MM.DD"
