I need to migrate users from drupal 6(old site) to drupal 7(new site) alongwith User Profile from Profile module

I am looking at documentation given in migrate module as follows:


On Subsequent pages at After adding new migrations, or making changes to the arguments of previously-registered migrations, if you want them to be recognized by Migrate, you need to:

Clear the Drupal cache, so any new classes are added to the Drupal cache registry. Perform the registration, either with drush migrate-register or by visiting admin/content/migrate/configure and clicking the "Register statically-defined classes" button.

I have created migrate_xyz.info ,migrate_xyz.module and migrate_xyz.migrate.inc files As mentioned above when I move to admin/content/migrate/configure i get a blank screen

Is this the right way to go for migrating users from drupal 6 to drupal 7? Or should I use some other module like migrate_d2d

    Well, migrate_d2d also depends on the migrate module. I think you might have missed something while implementing the migration classes. Or it might be a simple syntax error. It is very hard to tell when you get a WSOD. Follow the instructions given at drupal.org/node/158043, to debug what the issue might be.

Check this article . It describes how to use migrate module and it's API. Code from this article:

First of all we need to create module by adding folder with name my_migration adding my_migration.info and my_migration.module files. So lets start, code below will have a lot of comments:

//my_migration.info file

name = "User Migrate"
 description = "Migration of data from Drupal 6 to Drupal 7"
 package = "Custom Migrate"
 core = 7.x
 dependencies[] = migrate
 dependencies[] = migrate_extras
 dependencies[] = field
 dependencies[] = file
 dependencies[] = text
 dependencies[] = path
 dependencies[] = taxonomy

 files[] = includes/users.inc

//my_migration.module file
// this file can be empty but we will define some constants
<!--?php /*
 * Define some constants to use in class
define("SOURCE_DATABASE", 'd6_latest'); // Put drupal 6 db name you should also add settings to settings.php
define("CONNECT_NAME", 'migrate');// name of connection to drupal 6 db in settings.php
define('SOURCE_TERM_GARDEN_CAT', 3); // When we will migrate terms we will use it.
define('SOURCE_URL', 'http://path_to_drupal6.site');
define('MIGRATE67_SITE_DIRECTORY', 'public://');

//my_migrate_migrate.inc you should name this file as module_name_migrate.inc 
// if not your migration won't be autoloaded.

 * Implements hook_migrate_api().
function my_migrate_migrate_api() {
  $api = array(
    'api' =?--> 2,
    'migrations' => array(
      'MfUserMigrate' => array('class_name' => 'MfUserMigrate'),

  return $api;


<!--?php /**
 * User migration class to migrate users.
class UserMigrate extends Migration {
  public function __construct() {
    // Select fields from the Drupal 6 user table.
    $query = Database::getConnection('default', CONNECT_NAME)
      -?-->select('users', 'u')
      ->fields('u', array('uid', 'name', 'pass', 'mail', 'created', 'access',
        'login', 'status', 'picture', 'init'));
    // This is supposed to get roles not sure how.
    $source_fields = array(
      'uid' => t('User ID'),
      'roles' => t('The set of roles assigned to a user.'),
    // Set source and destination.
    $this->source = new MigrateSourceSQL($query, $source_fields);
    $this->destination = new MigrateDestinationUser(array('md5_passwords' => TRUE));
    // Set up database maping.
    $this->map = new MigrateSQLMap($this->machineName,
        'uid' => array(
          'type' => 'int',
          'unsigned' => TRUE,
          'not null' => TRUE,
          'description' => 'D6 Unique User ID',
          'alias' => 'u',
    // Add simple field mappings
    $this->addFieldMapping('uid', 'id_to_preserve');
    $this->addFieldMapping('name', 'name')->dedupe('users', 'name');
    $this->addFieldMapping('pass', 'pass');
    $this->addFieldMapping('mail', 'mail')->dedupe('users', 'mail');
    $this->addFieldMapping('created', 'created');
    $this->addFieldMapping('access', 'access');
    $this->addFieldMapping('login', 'login');
    $this->addFieldMapping('status', 'status');
    $this->addFieldMapping('init', 'init');
    $this->addFieldMapping('roles', 'roles');
  // Set up Roles.
  // massage the user roles before saving
  public function prepareRow($current_row) {
    $source_id = $current_row->uid;
    $query = Database::getConnection('default', CONNECT_NAME)
      ->select('users_roles', 'r')
      ->fields('r', array('uid', 'rid'))
      ->havingCondition('r.uid', $source_id, '=');
    $results = $query->execute();
    // add the anonymous role for everyone
    $roles = array('1' => '1');
    foreach ($results as $row) {
      // adjust the old to new role id's
      // Editors (rid 7) need role id 4
      if ($row->rid == 7) {
        $roles['4'] = '4';
      elseif ($row->rid == 4) {
        // producer from 4 to 5
        $roles['5'] = '5';
      elseif ($row->rid == 5) {
        // blogger from 5 to 6
        $roles['6'] = '6';
      elseif ($row->rid == 8) {
        // freelancer 8 to 7
        $roles['7'] = '7';
      else {
        // Collaboraters are role id 5 in both old and new dbs
        $roles[$row->rid] = $row->rid;
    $current_row->roles = $roles;
    return TRUE;
} // close the ourUserMigration class
