"Kibana server is not ready yet" and Kibana index migration

[dougburks]

Several folks have experienced issues after upgrading with Kibana displaying Kibana server is not ready yet even after waiting a few minutes for it to fully initialize. In most cases, this is a fairly simple issue with Kibana index migration and is quickly resolved by following the steps at https://docs.securityonion.net/en/2.3/kibana.html#diagnostic-logging.

This is a common issue when upgrading the Elastic Stack (not just with Security Onion). It looks like Elastic has fixed this in Kibana 7.12, so hopefully this won't be an issue for future upgrades.

Worked like a charm for me, thanks for the link to the fix Doug !

@corrcorr Since your Kibana logs do not indicate an issue with Kibana index migration, please create a new Discussion instead of replying to this one. Thanks!
