Problem: What will happen if I change the slug of a custom post type?

Solution:
1. The posts you have already created in this post type will not be lost. They will be migrated into the new post type automatically.
2. Any hard-coded links that were already created using the old slug must be updated.
3. Any post relationships for posts in this post type will be saved in the database, but you must to update any related post types in Toolset > Post Types to restore those relationships.
4. Any shortcodes you have placed that implement your post type slug must be updated. This includes Filter Controls, Loop Output contents, shortcodes placed in post content, conditionals, etc. These will not be automatically migrated for you.
5. Any custom code you have added to a functions.php file must be updated to use the new slug.
6. Any ancestor references using the "$slug" operator must be updated to use the new slug.
7. Any View or WordPress Archive that included the old post type must be resaved, since the old post type no longer exists. You must check the post type again.
8. Related taxonomies and custom fields must be resaved to point to the new slug.
...these are the top things that come to mind. You should always make a backup of your site before attempting this kind of change.
