I recently found that an older, now disabled plugin that made scheduled posts was creating new posts as pages. I went into the database and changed `post_type` to `post`.

The urls then changed to the permalink structure I have for posts:

> 
> <http://www.domain.com/default-category/this-is-the-post>
> 
> 
> 

Whereas the page URL was:

> 
> <http://www.domain.com/this-is-the-page>
> 
> 
> 

My old page URLs, which were shared on social media already, are now generating 404 errors. Most tutorials I find online discuss setting up redirects when the permalink settings themselves are changed and the whole site is affected. I just want to mitigate these few page-to-post URLs.
