I need to change my url structure to include an id so I want to just do it the way I should have done it when I started.
Right now I am simply using: %postname%
I want to change it to /topic-%year%%post_id%/
So the urls would go from /this-is-a-sweet-topic/
How would I 301 redirect the this-is-a-sweet-topic/ to the new url via .htaccess?
