While working with custom post types in WordPress, many times we come across the need to change the post type of a particular post.
It can be done either directly through code or using a plugin.
wp_update_post can be used when updating multiple fields of a post.
In case, only post type has to be changed, then
set_post_type is sufficient.
set_post_type along with the post id and you are done.
