It is going to be a very difficult task for you to relink all the images, check this link oh how to relink images with Lightroom
I believe the best thing to do in this situation would be to start from scratch , re import all images into LR and start processing them.
Hi Rohit, thanks for the help and link. I tried that option and it works great for mapping one file at a time. Only other question I have is on whether LR5 recognizes or more file based on the meta data mapping. Since I have a lot of raw files recovered, I was curious if there is any solution where LR automatically knows the files based on the metadata although file names are not the same as what it was in the original catalog?
thanks again for your prompt response and help!!!
While I am of the belief that it is possible to write a program that would match files based on metadata (other than the file name), I am not aware of any such program (and so your homework assignment is to do a search of ightroom plug-ins on the Internet).
But if you have to do the locating of renamed photos using the methods in Lightroom, I think you will have to do this one photo at a time.
