[Resolved] Migration and Post Type Rename

Hi,

I have an issue on my wordpress with a custom post type that was created, it was created incorrectly and posts where being stored with Block Recovery Validation issues. The solve required to rename the custom post type so everything was consistent.

The issue is we I have 300 posts that will all be affected.
I've updated the custom post type from the name of news_release to news-release. Soon as I do that, I lose the connection between my EN and FR posts. They are both still present in the database (actually the entries are in now doubled in the database). The EN and FR posts are essentially now acting like EN posts. I need to make this update and ensure I'm not losing the relationship netween the EN and FR posts for the custom post type.

I made the update with the following logic:

function rename_news_release_post_type() {
$args = array(
'post_type' => 'news_release', // The old post type slug
'posts_per_page' => -1, // Retrieve all posts
'post_status' => 'any', // Include posts of any status
);

$news_release_posts = new WP_Query($args);

if ($news_release_posts->have_posts()) :
while ($news_release_posts->have_posts()) : $news_release_posts->the_post();
$post_id = get_the_ID();
set_post_type($post_id, 'news-release'); // Change to the new post type slug
endwhile;
endif;

wp_reset_postdata();
}

I noticed the posts are doubled after updating the settings to include the custom post type news_release

How can I possibly solve this issue?
