You need to link to those new URLs from the pages of your site.

Additionally, set up a new redirect from the old to new URLs. This will fix links that searchengines have already indexed.

I assume you have a rewrite currently taking the old URL requests and fetching content. Adjust that rewrite to that it works for the new URL requests.
