Wordpress Permalink Structure 301 Redirect

Question

Currently I am using Wordpress v3.4 and using the following Permalink Custom Structure

/%category%/%postname%-%post_id%.html

Now I want to remove .html from it so I did like this

/%post_id%/%postname%/ 

I want to 301 redirect from old structure to new one.

Does anyone have the solution or suggestion?

Answer 1

Just use Redirection WordPress plugin to manage 301 redirections, keep track of 404 errors, and generally tidy up any loose ends your site may have.

Answer 2

Honestly, you should have never had put the extension, honestly I am surprised that Wordpress allowed this. However, if you change the permalink structure, usually it updates all previous posts and pages. Is that not the case here?
