I had deployed kibana-6.6.1-oss and created some visualizations, index patterns and dashboards in kibana.
My .kibana_1 was created as shown below:
I upgraded my ELK cluster to 7.0.1 (oss). All my data is retained but I see .kibana_1 index document count has decreased.
And on the UI i see all my visualizations & dashboards have been deleted.
Is the kibana index deleted on upgrade?
In kibana logs after upgrade, i see this
{"type":"log","@timestamp":"2019-07-04T10:10:25Z","tags":["info","migrations"],"pid":1,"message":"Creating index .kibana_1."}
{"type":"log","@timestamp":"2019-07-04T10:10:26Z","tags":["info","migrations"],"pid":1,"message":"Pointing alias .kibana to .kibana_1."}
{"type":"log","@timestamp":"2019-07-04T10:10:26Z","tags":["info","migrations"],"pid":1,"message":"Finished in 1295ms."}
How can i retain the data stored in .kibana_1 index from previous cluster?
