You can reassign a computer that is already registered with Microsoft Entra ID and is managed by Jamf Pro to a new user at any time.
Before reassigning a computer that is registered with Entra ID and managed by Jamf Pro, Jamf recommends that you do the following:
Remove the Jamf-related components from the computer.
Delete the computer from the Entra ID and Intune portals.
For instructions on removing Jamf components from a managed computer, see Components Installed on Managed Computers in the Jamf Pro Documentation.
