I delete my old indices from Elasticsearch and I noticed that this action also delete (remove) the index pattern that I had created on Kibana dashboard.
Can anyone explain me how those actions connected and why that happened?
And if so, how I can delete my old indices without delete the created patterns ?
Index Patterns are stored in Saved Objects, Saved Objects are written to your .kibana index. If you delete the .kibana index, you'll lose the associated Saved Objects as well. You can read more about the Saved Objects API here. If you wanted to do something like export an index pattern for potential use in a new .kibana index, you can read about that here.
