Listing all URLs for a Drupal site - for 301 redirect from old site

Hello,

I am using Xenu's Link Sleuth (PageRank 7) to generate a list of URLs for a drupal site (and also find all the broken links). I am migrating a site to Drupal CMS and need to map the old URLs to the new URLs using a 301 redirect to move over all the SEO ranking values to the new URLs. Using Xenu's Link Sleuth has always been helpful but I was really surprised when I saw hundreds upon hundreds of URLs that are dynamically generated by Drupal.

Is there anyway to get a shorter list of the URL for 301 redirect purposes. I know I could use URL alias to list all the aliased URLs but that would not catch all the non-aliased paths.

All the best,
Guy Saban
