I'm trying to upgrade a 5.4 cluster to 7.3.
- I first upgraded to 5.6.16 to get access to the Upgrade UI in Kibana
- That worked fine, and I was able to run the Reindex helper tasks and see the indices status change in the Cluster Upgrade view
- Then I installed 6.8 but Kibana gives an error on start-up of;
Any ideas ?

Hi there! This occurs because the `.kibana` index wasn't migrated to 6.x before upgrading Kibana to 6.8. There are some solutions here: [https://github.com/elastic/kibana/issues/14934#issuecomment-344298224](https://github.com/elastic/kibana/issues/14934#issuecomment-344298224). The second option would be the easiest solution (manually migrating the index per [https://www.elastic.co/guide/en/kibana/6.0/migrating-6.0-index.html](https://www.elastic.co/guide/en/kibana/6.0/migrating-6.0-index.html)).
