also, the problem is that all the topics after the migration were not only closed, but fixed. A forum displays the latest topics at the end of the list. I will be grateful if you help to solve the problem

Please backup the _wpforo_topics and _wpforo_posts tables and execute these two SQLs. Make sure the wp_ prefix matchs to your database table prefix.:

UPDATE `wp_wpforo_topics` SET closed = 0;
UPDATE `wp_wpforo_posts` SET is_answer = 0;

Then navigate to Dashboard > Forums > Dashboard admin page and click on the [Delete all caches] button.

Thank you very much. Topics have become open. But now everyone has become fixed. Is there the same request to unpin the topics.

I don't think all issues of your migration can be fixed with SQLs. I see the migration was done without understanding wpForo topic and post table column means. I'm afraid all your topics and posts are also private and unapproved. So I provide these SQL commands to set all topics and posts not-sticky, public and approved. Please backup topic and post tables and use these SQLs:

UPDATE `wp_wpforo_posts` SET private = 0, status = 0;
UPDATE `wp_wpforo_topics` SET private = 0, status = 0, type = 0, has_attach = 0;

Then navigate to Dashboard > Forums > Dashboard admin page and click on the [Delete all caches] button.
