I just upgraded Splunk ES from 6.2.0 to 7.0.1 on Splunk Core version 8.1.5.
However, some of the dashboards like Cloud Security, predictive analytics, Executive Summary, SOC Operations are not visible in any navigation menus.
While, the exec summary and soc operations dashboards are accessible ES app's dashboords page, however, others such as predictive analytics and cloud security are not. Infact, cloud security does not show up as a navigation menu option.
