Hi all,  
i have problem which kibana 7.5.  
After i update from 6.8 to 7.5 i have 3 problems/info

```
FATAL Error: [elasticsearch.ssl.verify]: definition for this key is missing

FATAL Error: [elasticsearch.url]: definition for this key is missing

FATAL Error: Index .kibana_task_manager belongs to a version of Kibana that cannot be automatically migrated. Reset it or use the X-Pack upgrade assistant.

```

Then i think, i can delete all index .kibana because is Dev env. so

`curl -XDELETE http://localhost:9200/.kibana*`

and now i have

`FATAL [class_cast_exception] java.lang.String cannot be cast to java.util.Map :: {"path":"/.kibana_task_manager_1","query":{},"body":"{\"mappings\":{\"dynamic\":\"strict\",\"properties\":{\"config\":{\"dynamic\":\"true\",\"properties\":{\"buildNum\":{\"type\":\"keyword\"}}},\"migrationVersion\":{\"dynamic\":\"true\",\"type\":\"object\"},\"type\":{\"type\":\"keyword\"},\"namespace\":{\"type\":\"keyword\"},\"updated_at\":{\"type\":\"date\"},\"references\":{\"type\":\"nested\",\"properties\":{\"name\":{\"type\":\"keyword\"},\"type\":{\"type\":\"keyword\"},\"id\":{\"type\":\"keyword\"}}},\"task\":{\"properties\":{\"taskType\":{\"type\":\"keyword\"},\"scheduledAt\":{\"type\":\"date\"},\"runAt\":{\"type\":\"date\"},\"startedAt\":{\"type\":\"date\"},\"retryAt\":{\"type\":\"date\"},\"interval\":{\"type\":\"text\"},\"attempts\":{\"type\":\"integer\"},\"status\":{\"type\":\"keyword\"},\"params\":{\"type\":\"text\"},\"state\":{\"type\":\"text\"},\"user\":{\"type\":\"keyword\"},\"scope\":{\"type\":\"keyword\"},\"ownerId\":{\"type\":\"keyword\"}}}},\"_meta\":{\"migrationMappingPropertyHashes\":{\"config\":\"87aca8fdb053154f11383fce3dbf3edf\",\"migrationVersion\":\"4a1746014a75ade3a714e1db5763276f\",\"type\":\"2f4316de49999235636386fe51dc06c1\",\"namespace\":\"2f4316de49999235636386fe51dc06c1\",\"updated_at\":\"00da57df13e94e9d98437d13ace4bfe0\",\"references\":\"7997cf5a56cc02bdc9c93361bde732b0\",\"task\":\"a7206eba37aaea59ba083a079fd80b65\"}}},\"settings\":{\"number_of_shards\":1,\"auto_expand_replicas\":\"0-1\"}}","statusCode":500,"response":"{\"error\":{\"root_cause\":[{\"type\":\"class_cast_exception\",\"reason\":\"java.lang.String cannot be cast to java.util.Map\"}],\"type\":\"class_cast_exception\",\"reason\":\"java.lang.String cannot be cast to java.util.Map\"},\"status\":500}"}`

This env is upgrading from 5.4 to 5.6 (x-pack change index[reindex]) -\> 6.8 and now 7.5.

If i delete all index kibana should not be clean installation now ?.  
I have a problem with permissions?

@Fin4l after deleting the `.kibana*` indices, did you restart the Kibana server? If so, are you still seeing these errors?

Based on these errors:

```auto
FATAL Error: [elasticsearch.ssl.verify]: definition for this key is missing
FATAL Error: [elasticsearch.url]: definition for this key is missing

```

You'll need to rename `elasticsearch.url` to `elasticsearch.hosts` and `elasticsearch.ssl.verify` to `elasticsearch.ssl.verificationMode`
