How to merge 2 iTunes libraries
I have one of the ancient original iPods that has my iTunes music from years ago. I also still have the old Dell desktop PC that has the old original iTunes library. I also have a new HP laptop and a new iPhone SE 2020 - they share a newer iTunes library. I want to merge the old library onto the new HP laptop without losing the new music. How do I do that? My new HP laptop and my new iPhone SE 2020 do show up as devices connected to my iTunes account. But my old Dell desktop PC and my ancient iPod do not show up as connected to my iTunes account.
Can I attach the old iPod to my new HP laptop and somehow merge the music from the old iPod into the iTunes library on the HP laptop without losing the newer music that is currently on the HP laptop iTunes library? And without messing up the new iPhone SE info that is backed up on the HP laptop?
Thanks!!
