You would be moving MDMs, so you would have to unenroll each computer from Jamf Pro and re-enroll it in to Jamf School.  

Thank you 

Yeah I just did this over the summer and you have to unenroll from one MDM and re-enroll into the new one, Since we did it over the summer I changed the MDM in Apple School Manager to Jamf School and then wiped the devices, and then they were enrolled in Jamf School. Then my summer students added them back into the Device Groups and scoped the profiles and apps. 

Lots of work.
