There is often the use case that you want to duplicate device profiles to adjust this for a certain device group / use case or just to have a separation of the name for different device classes.
There has been a user voice with over 1200 votes since 2017, unfortunately this feature has not been added to the MEM console yet.
To have an work around for this I created a small script that helps to copy a configuration profile. You can find this script on my Git hub repository: Copy-DeviceConfigurationProfile.ps1
Stay healthy, Cheers
Since Service release 2111 (Nov 15 2021) there is a option to duplicate setting catalog policies. All other policy types are not supported.
