Drupal - Disable pathauto for nodes created with migrate module

You basically need to make sure the $node object is passed in with pathauto set to false when it is saved.

In your migration class:

function prepare(&$row) {
  $row->path['pathauto'] = 0;
}

$this->addFieldMapping('pathauto')->defaultValue(0);

Works for me. Pathauto: Perform aliasing (set to 0 to prevent alias generation during migration See 'drush ma' + name of your class for full description
