Code:

javascript:(function() {
    var logout_re = /[\s\S]*Log.*out.*[\s]\s*(.*)\s/m;
    var links = document.getElementById('footer').getElementsByClassName('links')[0].getElementsByTagName('li');
    var user_name = links[links.length - 1].textContent.replace(logout_re, '$1');
    var evt = document.createEvent('MouseEvents');
    evt.initMouseEvent('click', true, true, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);
    document.getElementById('bz_assignee_edit_action').dispatchEvent(evt);
    document.getElementById('assigned_to').value = user_name;
    document.getElementById('commit_top').click();
})();

1. Drop and run this script in the root wpmu directory:

<?php
define('WP_INSTALLING', true);
require_once('wp-load.php');

$old_domain = 'olddomain.com';
$new_domain = 'newdomain.com';

$query = "UPDATE wp_site SET domain = '$new_domain' where domain = '$old_domain'";
$wpdb->query($query);

$query = "UPDATE wp_blogs SET domain = REPLACE(domain, '$old_domain', '$new_domain')";
$wpdb->query($query);

$querystr ="SHOW TABLES LIKE 'wp_%_options'";

$tables = $wpdb->get_results($querystr, ARRAY_N);

echo count($tables);
$query = "";
if ($tables){
  foreach ($tables as $table){
    $query = 'UPDATE '.$table[0]." SET option_value = REPLACE(option_value,'$old_domain','$new_domain')";
    $wpdb->query($query);
  }
}
?>

2. Edit wp-config.php and set “DOMAIN_CURRENT_SITE” to the appropriate domain.

That’s it, everything should work properly.

The command assigntome, by default, changes the assigned to field to your user. The whole process can be automated by tacking on the submit noun, which will simulate clicking the “Commit” button.
