I have recently installed Kibana4 but I am beginning to understand that dashboards are designed differently from Kibana3 i.e., to embed multiple visualizations which are designed individually into every dashboard. I already have a lot of dashboards designed in Kibana3 so I would like to know if there is a way to load them to kibana4 instead of creating everything from scratch.
To the best I know, there is no way to do that. Not just the formats, but the queries sent to ES backend are quite different. Kibana 3 used to use facets a lot for segmentation which is a deprecated feature and Kibana4 got rid of that.
