    A CakePHP implementation of josh.trow’s solution:

    class DetailsController extends AppController
{
    var $uses = array('Detail','DataDetail');

    function import()
    {
        $max = $this->Detail->find('count');

        $offset = 0;
        $limit = 10000;

        do {
            $exportedData = $importableData = array();

            $exportedData = $this->Detail->find('all', array(
                'order' => 'Detail.id',
                'limit' => $limit, 'offset' => $offset
            ));

            foreach($exportedData as $k => $row) {

                $importableData[] = array('DataDetail'=>array(
                    'id' => $row['Detail']['ID'],
                    'name' => $row['Detail']['name']
                ));
            }

            $this->DataDetail->saveAll($importableData,array('validate'=>false));

            $offset += $limit;

        } while ($offset <= $max);

        $this->flash(__("The details have been imported.",true));
    }
}

    Reduce the size of $limit as needed to accommodate your memory constraints. You’ll probably also need to increase the max_execution_time configuration variable in php.ini, as cycling through 1.2M records will take awhile.

    NB: I definitely don’t recommend this solution unless you need to perform this operation frequently and without human intervention.

    NB2: I should note as well that Cake lacks the capability (natively) to aggregate many rows in a single INSERT, so this solution will perform as many queries against your MySQL DB as there are rows in your MSSQL DB. Using Cake for this is entirely unnecessary, and my solution should be considered nothing more than a proof of concept.
