[datoadamia (David)]

Dear Friends!
Pelase, Help me, when I upgrade my Elastisearch from 7.4 to 7.5 I have error message in Kibana log:

logstash kibana[1918]: {"type":"log","@timestamp":"2019-12-05T18:11:18Z","tags":["info","migrations"],"pid":1918,"message":"Detected mapping change in "properties.space"

and
Kibana server is not ready yet

Plase, Help me

We deleted kibana indexes
curl -XDELETE http://localhost:9200/.kibana*
and restart kibana

It works!

Thank you

Yes, It works well after delete the .kibana* indices.

But, all saved objects (sapces, settings, dashboards, visualiations) were deleted. so you must export these all saved objects before do the XDELETE.

[CDuv]

How do you export Kibana settings before deleting the .kibana* indices when Kibana cannot start because of thoses bad .kibana* indices?

[David_Adamia]

unfortunately, I have not exported Kibana objects, so I had to create them again
