Dear Jorah,
There is an option in 'User Management' to Transfer Assets. Can you try that?
Based on the link Transfer user account items it was said that rights to scheduled reports cannot be transferred, but i guess recent updates made these possible.
Go to 'User Management' in Admin Interface of Adobe Analytics >> Click on 'Edit Users' under Users Category >> Click on the 'User ID' and click on the 'Transfer Assets' option >> You should see 'Workbook' which should have the list of 'Schedule Reports' and everything the User owns. Try it and see if it works!
Thank you
Arun
