- Move or assign any post into specific post type
- After successfully assign to post type post data will remain same in the post like post title, post content
- Works with custom post types
```
$post_id = 123; //your post id
$post_type = 'page'; //your post type name also you can use custom post type

if ( set_post_type( $post_id, $post_type  ) ) {
  printf( __( 'Post %d is now a %s', 'textdomain' ), $post_id, $post_type );
} else {
   printf( __( 'Impossible to transform this post into a %s', 'textdomain' ), $post_type );
}
