[[upgrade-new-install]] === New Installation Kibana 4.0 introduced a major architectural overhaul. As a result, the underlying `.kibana` schema changed so significantly that upgrading from Kibana 3.x requires recreating all visualizations, dashboards, etc. If you're upgrading from 3.x, please follow the <> to install Kibana from scratch, and then manually recreate your searches, visualizations, and dashboards.
