How to update cross references when duplicating book files?

I have a book with multiple files, containing hundreds of cross references.

I want to copy/duplicate this book, including the files within, and move them to a new location (from my local computer to Google Drive).

But after I copy the files to Google Drive, the cross references in the copied files point to the original files on my local computer.

Is there a way to update all the cross refernces, to make them point to the new files instead of the old ones?

I tried copying the book file itself and then use "replace document" from the book palett, to replace each separate file.
I also tried creating a new book file, and add the new files into it. Every time I end up with the same result: the cross references within the new files are still pointing to the original files.

Any help would be highly appriciated!
