I'm looking for a way for merging Forum threads and moving comments posted to the wrong thread into the right one.

I did a bunch of searching and finally found the "Comment Mover" module which appears to do what I need. However, it's only available for D7. https://www.drupal.org/project/comment_mover

Is there any Drupal 8 (or 9) equivalent to the D7 "Comment Mover" module? Or another solution for the problem of merging Forum threads etc?

Thank you.

I tred to move Drupal 8 files from the subfolder to the root. But it gave the following error messages.  Then, I reversed the process.  Could anyone suggest what could be the best way to start showing a site that is actually in a subfolder instead of in the root directory?  Manua;lly moving files and folders gives the following error messages.

I am trying to retrieve a previous Drupal 8 site that I had stopped using some time ago. But, now I would like to republish it for some reason. I can see the website. But the images on the front page are not showing anymore. Could anyone please let me know how to start seeing these images? The link to the website is as follows.
