How to convert a second iTunes library in catalina
I have a second iTunes library I want to convert after Catalina. The instructions Apple provides says to just hold down Option when starting iTunes, just like before, and then select the library. I do that, and select my iTunes library folder (just like before), and nothing happens. The dialog box just move down a level in the folders. I have tried selecting other sub-folders, like iTunes Music. Nothing happens except I move down another level in the folders.
I saw a thread that said, in the Catalina beta (back around June), you could only convert the iTunes library that was selected when you upgraded. It was hoped that this would be fixed. The advice then was, if you use the beta, make sure you have your main library selected. What I am experiencing now seems like the problem was not fixed. Unfortunately, I had my secondary library selected when I upgraded.
