Forgot to deactivate old computer's product key before transferring the product key to another computer

Hi, I've purchased a free Windows 10 Education license from my university a year ago. Lately I've bought a new computer that came with Windows 10 Home pre-installed. I've tried to transfer my win10 education product key to this new computer
but I've forgot to deactivate the key at my old computer before traded it in, and now my new computer is in notification mode. Is there any alternative besides purchasing another education license?
