Full cluster restart upgrade : Stop indexing and perform a synced flush

Elastic Stack Elasticsearch
1

I am trying to do an update Elasticsearch from 5.6.3 to 7.0.0. I am referring to the following guide for it:

https://www.elastic.co/guide/en/elasticsearch/reference/current/restart-upgrade.html

The browser is throwing following error on step 2: Stop indexing and perform a synced flush.

{"message":"closed: [index_closed_exception] closed, with { index_uuid="Q9-Fk8hdT5CqQyGUDKDtoA" & index=".kibana_1" }","statusCode":400,"error":"Bad Request"}

You can't upgrade from 5.x to 7.0 directly. Indices are not compatible and must be upgraded in 6.7.x first.

My bad, I wrote '5.6.3' instead of '6.5.3'. The current version I'm using is 6.5.3

You should upgrade to 6.7.x and use the upgrade assistant in Kibana to see what you need to fix if anything.
