Questions about upgrading from 5.6 to 6.x (part 2)

[waynesmallman]

Please note that this discussion came at the request of a Elasticsearch personnel, via a conversation on Twitter, in relation to a previous discussion regarding an upgrade from 5.6 to 6.x.

So, the question that wasn't answered (at least not so that I understood it) is whether an upgrade from 5.6 to 6.x would affect the index data?

Also, since we need to change the schema (having removed the dependences on the type field), would those changes to the schema affect the index data?

It won't, no.

Data created in a 5.X cluster will work in a 6.X cluster.
If you want to create a new index then you will need to update the mapping (schema).

Hi @warkolm, based on this we're going ahead with the upgrades. Drum roll...

I'll respond with the results!
