I've been looking for a solution to be able to change my website's urls from:
I've looked for a LONG long time. And so far, none of the solutions actually will take the user from the /archives/%post_id% to /%postname%/ no matter what I've tried. I usually just check really quickly to see if the /archives/%post_id% link actually re-directs to the /%postname%/ because there are thousands of links on Facebook, Twitter and Google+ to my stories that help with the SEO.
Your plug-in seems like it would be able to do this sort of thing, as that's what it appears to claim to do. Am I reading it right? When a pages url changes, the system automatically redirects the old recorded url to the updated url?
