Nearly all menu links ignored

I solved the problem. In the migration I created a new menu for my old nav menu, which includes most menu links created thru the UI that point to site content.

Nothing in the documentation discusses mapping old menus to new ones. Migrate_d2d maps primary-links to main-menu and secondary-links to user-menu(?)' but not the others.

It's not a problem. I figured out what I did wrong.

I think there is a need for some documentation. That is a todo in the handbook pages.

Here's what I did.
1. Create a map of menus on the D7 site that correspond to menus on the D6 site.

  // D7 machine_names on the left.
  protected $sourceMenus = array(
    'devel' => 'devel',
    'features' => 'features',
    'main-menu' => 'primary-links',
    'navigation' => 'navigation', 
    'user-menu' => 'secondary-links',
    'site_menu' => 'menu-global-nav',  // this is where your site-specific menu will go.
  );

Then I pirated the menu and menu_links classes from migrate_d2d, replacing the following code at the bottom of the menu.inc file:

    // D6 prefixes menus added through the UI with 'menu-'
    if ($row->menu_name == 'secondary-links' ||
        substr($row->menu_name, 0, 5) === 'menu-') {
      return TRUE;
    }
    else {
      return FALSE;
    }

with the following:

    //Translate menu names
    $row->menu_name = rsb_migrate_get_menu_name($row->menu_name);

Then, in the menu_links.inc comment out the following:

    $this->addFieldMapping('menu_name', 'menu_name');

In the query for basic menu_links data add the following condition to get only links from the menus you plan to migrate:

    $query->condition('m.menu_name', array('menu-global-nav', 'primary-links', 'secondary-links'), 'IN');

In my case all of the site-specific links were in the D6 site's menu-global-nav.
In the code that steps thru the D6 site menu links replace the following:

    if (!($row->menu_name == 'primary-links' ||
        $row->menu_name == 'secondary-links' ||
        substr($row->menu_name, 0, 5) == 'menu-')) {
      return FALSE;
    }

    if ($row->menu_name == 'primary-links') {
      $row->menu_name = 'main-menu';
    }

with a call to the function that translates menu names:

    //translate menu names
    $row->menu_name = rsb_migrate_get_menu_name($row->menu_name);

That will create the new site-menu on the D7 site and migrate primary- and secondary-links menus. It will also rename the main- and user-menus. I'm sure there is a way to keep the D7 names, main-menu and user-menu, but I wasn't concerned enough to figure it out.

I hope this helps

You could put it above the construstor. If you have a my_migration.migrate.inc file you could put it in an abstract class. Then call it from node.inc.
