I see that there are a number of threads addressing this issue but no clear resolution.
Using the Blogger Import Tool of WordPress, it sees all of the posts but only a fraction of the comments (just over 700 when there are over 1500). Upon import of course most of the comments are missing.
There are 339 posts in the blog going back to 2007 and most of those posts have comments. It has imported all the recent comments going back to about November of 2009. Anything prior is missing.
I've tried most of the proposed solutions on this board such as import and re-import again and again, exporting the Blogger blog to an xml file and then using a converter (doesn't work because the file size is too large at 16+MB), and even playing a bit with blogger.php in the wp-admin/import folder.
I'm not a coder so I can't break up an xml file into smaller chunks or write scripts (well, I did go to film school). I'm looking for a somewhat elegant solution to the problem if anyone cares to share one.
