Transfer from (very) old iTunes to new(er)
I'm moving from a very old Mac to a somewhat newer (not really brand new) Mac. I want to move all my music from the old mac to the newer Mac, without losing album art, playlists, etc.
I have about 18,000 songs, about 200 GB total, all ripped from CDs, nothing synced via cloud services (don't want/need to), the two computers side-by-side with a shared network folder (and external drives I could use to move from one machine to another if that's easier/faster).
The old computer (where all the songs are) is an old cheese-grater Mac Pro, running 10.6.8 Snow Leopard. iTunes 11.4 (18). All music files are located in: Boot Drive > Users > [UserName] > Music > iTunes > iTunes Music...
The newer computer (where I want the songs moved to) is an iMac Retina 5K, 27”, Late 2015) running Mojave 10.14.3, iTunes 12.9.2.5. All music files (there are just a few, and I don't care about them, they can be blown away if needed) are located in: Boot Drive > Users > [UserName] > Music > iTunes 1 > iTunes Media > Music...
What's the right way to do this so the playlists, organizational details/metadata I have added, etc. (including album art I've attached to things) makes the trip and all is preserved? Any gotcha's I need to watch out for and avoid?
Thanks in advance for the guidance.
