I need to migrate/move my Entra Domain Services to new subscriptions. This operation is not supported by Microsoft. So I need to delete and recreate the service again with same configurations. I am looking for a workaround to take backup of users, computers and GPOs before deleting the managed domain and recreate all the ad objects again in new domain with the help of that backup.

I am unable to export the details because Microsoft doesn’t provide that level of control. Is there a way by which I can domain join machines again with the new domain without manually doing it for all the machines one by one. After deleting the managed domain I cannot login as domain admin into the domain joined machines and data also gets deleted.
