Three comments:

a) Did you 'Dump' or 'Export' - you can only 'Import' what you have 'Exported' The error message you quote suggests you me that you 'Dumped'

b) If you 'Export', then edit the filenames in the csv and then 'Import' on top of an existing database, what should(!!) happen is that the category records will be flagged as errors and ignored; the links that are unchanged will be untouched; the links which have new file names will be inserted; but the old entries will not be deleted.

c) If you empty the database after exporting the dump, the re-import should work fine. However, there are some fields (e.g. the thumbnail image, I think) which are not retained during this process.

d) There may be a much easier way to do this with a short bit of sql.
