Workflow mediathek

Will get my prime go next week. As my macbook is very old it seems the new engine software won’t work with it. So I try to find a way around😂 I did copy my Itunes mediathek already on a hd. Is it possible to connect the hd with the prime go and copy the mediathek to a sd card ( which I will get soon) with the prime go ? The prime go should do the analysis. Then if there are new songs to add, I just take a usb stick and export those files to the sd card on the prime go Other way around would be copy the itunes mediathek on a sd card and feed the prime go with it
