Hi,

When does kibana\_N+1 index gets created?  
Can kibana\_N+1 gets created if there are more than 1 replicas of kibana running.  
Is it possible that kibana index migration process get initiated between same elk version upgrade.

Thanks in advance.

We have documentation about what this is, and how to resolve failures, here: [https://www.elastic.co/guide/en/kibana/current/upgrade-migrations.html](https://www.elastic.co/guide/en/kibana/current/upgrade-migrations.html)

Thankyou for sharing the document.  
I just need to confirm if there is any way possible that kibana\_N+1 would get generated even if kibana migration process has not run.

It is possible, but uncommon. It could happen if you import Kibana saved objects from an older version, for example.
