Can Existing Comments be Allocated to a Different Post

Hi,
I recently changed web hosting providers, unaware of how the process really works and the active role I have to play in transferring my WordPress files etc. I tried to restore a backup of my files through WP DBManager, but that was unsuccessful, so now I am manually restoring my previous posts etc. However, it seems that the comments part of my database was restored. So now I have all these comments, which is great, since I did not loose it, but they are not linked to any posts. It seems that the comments now linke to the first random article or page I upload. I want to know, Is it possible to manually allocate or link these comments to the relevant post once I uploaded it?
