How to sync edits from folder on one hard drive to backup drive?

Apologies if this has been asked and answered elsewhere.  I couldn't find anything about it.

I recently had my main working hard drive go on the fritz for about a week.  This is the drive my LR catalog is on, and where I do all of my LR work. 

I have a backup drive, which is constantly updated.  When the main drive pooped out, I still needed to get work done, so I did my edits on the files located on the backup drive. 

Now that my main drive is back online, I'm wondering if there's a way to sync all the LR edits I made to the files on the backup drive to the respective files on my main drive.  I know sometime in the future, I'll need to revisit some of the files and I would like all my "working" files in one place. 

Thanks in advance!

All of the edits you have done are contained in the catalog, not in the files. So with the files that are back on your main hard drive are in the same folder structure as on your backup hard drive just right-click on your folder structure in the library module and update the folder location. Point Lightroom to the folders on your main hard drive and everything will be back in order. If you have moved the images around and they are in a different folder structure now you might have some difficulty getting things synchronized again.

That's perfect, thank you!  Exactly what I needed.
