KIbana "Kibana server is not ready yet" -- routing disabled during upgrade

Every time Kibana is restarted, it checks if a migration is required. It will perform a migration if either documents are outdated or if the mappings are different to what Kibana expects. The latter is what triggers a migration in your case.

As per the error message, properties.originId has a different mapping to what Kibana expects. Do you have any index templates that might have an indexPattern that matches .kibana*?

Could you share the output of GET /.kibana/_mapping?
