Since nearly two years now, the Cumulocity Cockpit application provides a flexible and extensible way to create responsive dashboards for your IoT data, effectively superseding the functionality to create own dashboards in the Cumulocity Device Management application.
Over the course of the next releases, we will be gradually deprecating and removing this functionality in Device Management. Starting with Cumulocity 7.44, it will not be possible to create new own Device Management dashboards. Your existing dashboards will still be available, giving you the opportunity to migrate them to the Cockpit application. The dashboards will be removed gradually over the course of the subsequent releases.
If you have question regarding about moving your dashboards, you are always welcome to contact support.cumulocity.com
