The old ASR files won't be any use unless you plan using the old map they are related to. They are just taking up space so better to delete them. While you are at it, delete the old JCV file. Each map update will have new ASR, JCV and 3d files. Also you should update the G2S and SQlite folder/files for 'complete' update. Again, the 'older' files can be safely deleted.
