Troubles starting kibana.service after the upgrade from 6.8.22 to 7.14.2

[Penchev (Petar Penchev)]

Hi,

I have the following errors when starting Kibana:

Jan 20 03:22:59 myserver kibana[30701]: Cannot update parameter [index] from [true] to [false],
Jan 20 03:22:59 myserver kibana[30701]: FATAL  Error: Unable to complete saved object migrations for the [.kibana] index. Please check the health of your Elasticsearch cluster and try again. Unexpected Elasticsearch ResponseError

I have tried this 7.12.0 upgrade migrations fail with timeout_exception or receive_timeout_transport_exception · Issue #95321 · elastic/kibana · GitHub, but it doesn't help.

Any ideas how to solve this?

Thanks!
P

Solved.
If nobody helps you help yourself.
Deleted all .kibana indices, restarted the kibana.service and Kibana UI is accessible.
