If you do not redirect those old urls to the new ones any sites that have links to those urls will instead be linked to broken pages.
Also, google will have to reindex all of your new urls if not redirected. That is not neccesarily a bad thing though unless you have incoming links. You will also take an seo hit until all of your new urls are indexed.
Dbseo does it pretty seamlessly though and will redirect all the Vbseo urls to your new ones. Great product.
