To move a device to another group
Click the Ellipses icon in the ACTION column of the group you want to move to another group, select Change Device Group.
Select the devices from the Source Group Devices list and click the right-caret icon to move the devices to the Destination Group Devices list.
When you move a device to a group that already has a template applied, the template configuration is made available to the newly added device. Commit and deploy the updates to apply the configuration to the device.
