Well, if all the files are supposed to be the same other than their  
names, why not try something like this:

$ cd orig_directory
$ md5sum * | cut -d ' ' -f 1 | sort > ~/orig.sums
$ cd new_directory
$ md5sum * | cut -d ' ' -f 1 | sort > ~/new.sums
$ diff ~/orig.sums ~/new.sums

That won't tell you everything but it will tell you a lot.  If, for  
instance, all the files ARE the same (just renamed), then there  
shouldn't be any differences.  If only a few lines are different,  
then you can probably manually track down those files.  If a lot of  
lines differ, then there was some serious problems with your export.
