Changed the permalink structure and don’t want to lose your SEO? You’re in the right place!
This plugin will automatically redirect the old ‘%postname%’ permalink structure to the new one as long you keep the same slug in the posts. It works by searching posts by the slug name that comes in the request, so as long as you keep the post slug intact, it should be able to find the post and redirect to whatever new permalink it now is.
Eg.:
Let’s suppose you’re using ‘/%postname%/’ as your permalink structure, but after some time you find out it’s not a good structure (it’s not!) and you change it to ‘/%category%/%postname%/’, the old links will now generate a 404 page, because there’s nothing there anymore.
