Update Elasticsearch 1.0 -> 6.4

Hello. I need advice - how to do it. I have an elasticsearch 1.0 on my test server. I want to upgrade to version 6.4. It is important to keep the server working. How should I do this with minimal losses? Update one by one to each major version or go straight to 6.4?

A test server? Running version 1?

Anyway, I'd try a reindex from remote. In 6.4 reindex what you have in cluster 1 basically.

I support the old project. I decided to try it on a test server before upgrading production.
I understand correctly - do you suggest using this method?


Thank you
