If it is possible I would be inclined to do two things.
1. Connect both computers on the same network (the same wifi or router(switch)). If a network is not available, back to back with an Ethernet cable (you may need a crossover cable but a lot of cards these days can sort themselves). You will need to put the ip addresses into the same range.
Once connected, share the folder on the old computer the create the folder on the new computer and copy across. Basically drag and drop.
2. While you’re at it create a backup of your music.
Then store your old computer for a while. Old files are like junk in a shed. Whatever it is you won’t want it until the day after it goes to the dump.
