I don't know about Apsona. But the CEON URI does not rewrite existing products/categories...or easypopulate uploads. You either have to manually update each product/category to generate your desired name/url, or purchase the CEON mapping manager module (is that it?) that will mass generate existing products.

Note that the developer recently passed away, so I'm not sure of the status of his modules, free or commercial:
