On the Device Status Summary page, select the row for the device that you want to export and click the edit icon (on the right corner)
On the Update Device page, select Export This Device (All Or Some Tests) To Another Department.
Select the Destination Organization for the device, enter the Device Name in New Organization, and then click Next. (The destination organization must be associated with the same user-class as the original organization.)
Select those tests that you want to export with the device, and then click Export Device.
Also note that when a device and all tests are exported to another organization, any new tests created after the export are not automatically exported or visible to the target organization.
Provisioning information for the device and exported tests are available to the destination organization for viewing.
