Oh, hey. I actually read a bit of your opening message, and noted that you’re transitioning computers. The method changes from time to time, based on OS, etc, but you can transfer the entire itunes database from one computer to another. Just do a search for it and you’ll find all sorts of instructive websites.
And for your future reference, I try to run my computer like this:
Main drive (SSD): OS and user apps, some user data, games, etc.
Secondary drive (HDD, Western Digital): two (or more) partitions
Partition 1: Documents, 3d printing files, pictures, etc.
Partition 2: Music, iTunes library, videos, etc.
Copy user data from SSD to the HDD often, so that it’s “backed up”. Make backups of the HDD occasionally (but I’ve never had a Western Digital drive fail, knock knock)
That way, next time I build a new PC, build PC with new SSD, then copy the contents to a new HDD and keep the old one as “backup”. Transfer iTunes library, and it’s good to go. Huzzah!
Yes I learned to do that maybe 10 years ago or so. I keep the OS and the software on a single C: drive, and all the documents on a second drive.
This was born out of necessity. A hard drive crash is a miserable thing. So when they crash or get some or another kind of conflict, I can just pull the C: drive and swap it without losing the documents, music, files etc. Just reinstall the OS and the software onto the new C: drive - which is time consuming enough.
I also have a number of backup portable drives. Since I don’t want to use the cloud(s), I manually sync multiple computers (home and work) so there are always 2 or 3 drives with the information.
