Hello all I am along the way of moving my blog via large-dump because of its huge size 30MB. However, if moving I recieve this error:

Error at the line 139: INSERT INTO `wp_commentmeta` VALUES (21620,13544,'akismet_as_submitted','a:67:{s:15:\"comment_post_ID\";s:4:\"6034\";s:14:\"comment_author\".....................continues..

I must know why this really is occurring and just how can one repair it.

Thanks ahead of time!

One can not be sure using the limited quantity of information you've given, however i think the dump file wasn't submitted or produced correctly. Most likely, there's a quality limit for uploading in your new server.
Attempt to have a compressed database dump and posting.
