how do i combine music libraries?
I am trying to move library from an old computer that has not been deauthorized to a newer computer that has already been used for itunes and has a current library, what steps should i take?
Windows 7
Assuming the new computer is authorised for the apple iD used on the old machine.
Copy the iTunes Media folder from your old machine to the desktop of your new machine
Then on your new machine File > Add to Library
This should now give you one library. When import has competed you can delete the folder from your desktop.
Alternatively you could use home sharing
