Export comments

What table does Disquz store comments in? wp_comments? How can we export comments from one domain to another, subdomain. The sites are identical, you just need to update the comments on the subdomain (they have accumulated on the main domain during technical work), and leave the rest untouched. We updated the articles on the subdomain, but not on the main site. How to extract only comments? Take them from the base and attach them to updated posts

Thanks
