Sometimes the canonical 404 guessing function can handle it. Not often.

There are plugins which can handle this though. Permalink Migration
and Permalink Redirect come to mind. Basically, they give you a config
page where you can put your old permalink string, and it will
recognize and send the user a 301 redirect to the new correct
permalink. This allows search engines to recognize that your
permalinks have changed and they will alter their URLs accordingly.
