 * Hi.
    On my site I have created a new post type: AZIENDE. Now I have nearly 1 
   million of posts. I wanted to change the post type slug, so I renamed the slug
   and clicked the option to migrate posts, see screenshot: [https://www.screencast.com/t/TE7CdJ01GVL3](https://www.screencast.com/t/TE7CdJ01GVL3)
   Having 1 million posts, the site times out and I see an error after some minutes.
   How can I do? Can it be done via cron?
 * Waiting,
    thanks.

 * Admittedly, I never bothered to test that functionality with that many posts.
   Never thought I’d need to 😀
 * Perhaps a better way, given that volume, would be to make use of MySQL instead.
   I suspect that’s going to be more efficient with time as well as have fewer timeout
   issues.
 * Something like this post looks like it’d work [https://stackoverflow.com/questions/17668138/change-name-of-a-post-type-without-losing-posts](https://stackoverflow.com/questions/17668138/change-name-of-a-post-type-without-losing-posts)
 * Of course, please do back up the database first.
