Hi All-
I recently upgraded from 5.6 to 6.8.6 and had some issues getting Kibana running. In the end I was able to get it running with deleting all the kibana indexes, deleting aliases to .kibana and then starting fresh. After that, I created a new index, pushed the mapping, reindexed my backup to that index and then updated the alias all while Kibana was running. My issue is, each time I try to restart it tries to 'migrate' again and it fails and then I have to do the whole process again.
I haven't been able to figure out exactly what is causing is, would anyone have some troubleshooting ideas to find what is wrong in my index that doesn't seem to be migrating correctly?
I think the general error I'm getting on startup is like this:
```auto

Can you do a \_cat/indices request and post the result here? (you can hide your personal indices, just interested in the system ones.)

I'm trying to figure out why there is a kibana\_8 index pattern. Did you change your default kibana index in the kibana.yml?

Hi-
This was just a manual copy/reindex from our Kibana 5.X index that keeps failing to migrate. So now whenever we have to restart Kibana we'll manually remove the ".kibana\_x" indexes, remove the alias from .kibana and then start fresh. Kibana creates a .kibana\_1 and .kibana aliases to it and then we just change the alias again "kibana\_8" that keeps failing migration but works if we change the alias while it's running.
Settings are default I think because its commented out:
`# Kibana uses an index in Elasticsearch to store saved searches, visualizations and`
`# dashboards. Kibana creates a new index if the index doesn’t already exist.`
`#kibana.index: ".kibana"`
