First off, I searched for this but was unable to find anything. If I am repeating an answered topic I apologize, I may have been searching the wrong keywords.
For quite some time after upgrading from Lightroom 1 to Lightroom 2, I was running both versions in parallel. For some strange reason, I was never able to get Lightroom 1 removed from my PC.
Time and time again, when I was being careless and not paying attention Version 1 would open and auto import my images. After the import was complete, I would go to open my secondary screen, and realize that I was in version 1. Afterward I would open Version 2, and re-import the images, since each version was operating off it's own catalog.
The root of the problem has been solved. I recently built a new computer, installed Windows 7 from scratch, migrated my current LR2 catalog to the new machine, and everything is good.
Searching my raw image file directory, I came to realize that EVERY photo that had a duplicate copy of the raw image was followed by "-2", for example I would have img_0055.crw, and img_0055-2.crw.
I searched my directory for file names containing "-2" and moved all of the duplicates out of my primary raw image directory to a temporary folder for safe keeping in case I needed them later.
The problem is, every one of these images in my current LR catalog points to the RAW file with -2 tacked onto the file name. Currently, I get a warning message that the original file can not be opened, I right click the image, choose show in explorer, and choose the appropriate file (IE, the same file name without the -2 on the end).
What I am looking for is an easy way to update my catalog instead of doing this image by image. If it were a standard SQL database, a simple query to find any image location that contained "-2" and remove it would take care of the issue. Is there a similar way to update the LR catalog?
Also, a mass update based on date would not be appropriate either, because at times I would open LR2 manually and do the import. As a result, images that were done with the auto import first then imported a second name contain the -2, but for the instances where I opened LR2 and started the import, the RAW files were not duplicated, and my current catalog points to the correct RAW file.
I know this is a unique, off the wall problem that I created for myself, I am just looking for an easy way out

Also, if I explained the situation poorly I apologize. I understand the issue, it's just kinda tough to describe accurately.
If anyone has any ideas, I would love to hear them.
