Can you use Update Tag from Library for this? I've not used it myself, but I'm guessing you could;
1. Turn Auto-Import off
2. Send your old files to the recycle bin using Windows Explorer
3. Again, using Windows Explorer, put your new files where your old files were (assuming these new files have the same filename)
4. Select the files in MC
5. Select Library Tools>Update Tags (from Library) from MC.
I'd try it on 1-2 files first, just in case.
