Reason, after updating, kibana creates new indexes?
Then I tried to remove .kibana_task_manager_2, and .kibana_2., i'll get new fresh kibana without my dasbords, spaces etc.
kibana_1 | {"type":"log","@timestamp":"2021-03-17T00:05:54Z","tags":["warning","savedobjects-service"],"pid":8,"message":"Another Kibana instance appears to be migrating the index. Waiting for that migration to complete. If no other Kibana instance is attempting migrations, you can get past this message by deleting index .kibana_2 and restarting Kibana."}
