Hi Gabar, FYI Few More Points About Licencing.
Cisco DNA Center can display graphical representations of your purchased DNA licenses, how many of them are in use (that is, assigned to devices), and their duration.
There are many ways to find and view license details in Cisco DNA Center. For example, you can click on the license usage and term graphs displayed in the Switches, Routers, Access Points, ISE, or All Licenses tabs in the License Manager window. Each of these will display popups with aggregated facts about licenses for each of these product families.
The simplest method for getting the most comprehensive license details for a single device is to use the License Manager's All Licenses table.
You can upgrade or downgrade the feature level of your device licenses. You can do this with DNA (subscription) licenses. Your feature level choices are either the basic Essentials level or the comprehensive Advantage level. (Note that Network license conversion is available for products in the Cisco Catalyst 9000 device family only and Network license conversion is handled implicitly when DNA license level is changed.)
Whenever you change a device's license level, Cisco DNA Center automatically downloads and applies your licenses behind the scenes, using your Smart Account.
As applying a license level change requires a device reboot, License Manager will prompt you to confirm that you want to reboot the device as soon as the license level change is complete. You can choose not to reboot with the license change, but you will need to schedule the reboot at a later time, or your license level change will not be applied.
