Hi, I am migrating Kibana from 7.5.2 to 7.17.0 and getting the following error when doing so. Kibana isnt starting up due to this failure and hence migration fails.

Hi @anburethy , based on the error message, the saved object `platform:dashboard:1234-530f-11ea-b8ea-sdf323232` cannot be migrated. It could be possible that this object is corrupt.
If so, you could delete this object from the `.kibana` index (i.e similar steps given in [Corrupt saved objects](https://www.elastic.co/guide/en/kibana/7.17/upgrade-migrations.html#_corrupt_saved_objects)).
Can you try this approach?

Thanks @ropc , I can delete the object but my Kibana is under migration and its not starting up now and I can revert as well now. So I wont be able to run a command in Kibana UI or curl. Any help on how to find and delete it manually from the server.

@anburethy - if the Elasticsearch cluster is running and is reachable, you should be able to run the required APIs (e.g Delete API) via curl, Postman.
