   So I'm working on a migration of a pretty big blog to WordPress. I've run one test import and it worked beautifully including tags and categories - impressive. However, the authors are completely screwed up. I have over 50 authors and none of the migrated posts are showing the correct author - it seems as if authors have been randomly assigned to the posts, I can't find any pattern. Anyone have any thoughts on this? Right now, wordpress hasn't been modified at all, just a totally vanilla template set, no plugins. I have re-run the import script and it still randomly assigns authors to posts....

   Responding to myself as I'd like to try this again.

   Any advice for a massive migration like this? 3500+ posts, 6000+ comments, 60+ authors?

   Should I do this in batches somehow?

   Thanks!

   okay, bam, failure due to some kind of memory overload. And once again the authors are randomly assigned to posts. any ideas how to set php to handle more?

   The error:

   Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 35 bytes) in /usr/www/users/...path..../wordpress/wp-includes/plugin.php on line 302

   I was having the same problem with a large WPMU import. I muddled about a bit and seemingly found a solution.

   The only caveat is that I am not creating new users with the script, and I haven't tested to see how this alters that function.

   I changed a line in /wp-admin/import/mt.php

   Line 106 changed from:

   $key = array_search($author, $this->mtnames); //find the array key for $author in the $mtnames array

   Line 106 changed to:

   $key = array_search($author, $this->get_mt_authors()); //find the array key for $author in the $mtnames array
