Wouldn't it be great if you could click a button and all devices from a particular OU (lets say "/Students/High School/Grade 9") moved to a given destination ("/Students/High School/Grade 10" in our example) ? I see this a wonderful addition for schools who want to keep devices in the same OU as students. GCDS (formerly GADS) can be configured to move users from one grade to the next, but it leaves the devices behind.
Include mappings of Source and Destination in a Modular window so that users can customize the automation flow. Include an "+Add another" for update paths (Grade 9 to 10, Grade 10 to 11, etc.).
All updates reference the data found in the Devices tab as authoritative to prevent cascading.(Move Device 1 from A to B then B to C, then C to D etc.)
