I have a question about incremental rules of the .kibana_N,
In the official documentation, Saved objects are stored in an index named
N is a number that increments over time as Kibana is upgraded.
The kibana that I currently use is not upgraded. (I understand 'upgrade' mean is the version update right?)
but I can see .Kibana_1, .kibana_2 index.
I am curious about how and when N increases.
