I have a single kibana instance. I just upgraded from 8.12 to 8.15 by stopping kibana with systemctl, dnf installed kibana, and then restarted kibana. Kibana is failing to start and is printing this error message:  
`Task security:endpoint-diagnostics \"security:endpoint-diagnostics:1.1.0\" failed in attempt to run: Saved object [task/secu rity:endpoint-diagnostics:1.1.0] conflict`. Does anyone know what may be causing this error message or recommend steps to investigate further/resolve?

Hi @6igwig,

Welcome back! Is there any particular reason why you didn't use the [upgrade assistant](https://www.elastic.co/guide/en/kibana/current/upgrade-assistant.html)? That would be my recommendation.

That looks like a saved objects conflict between the old and new version. Do you have a prior snapshot you can restore to [in order to revert](https://www.elastic.co/guide/en/kibana/current/upgrade-migrations-rolling-back.html) which would allow you to use the upgrade assistant?

Let us know!
