I want to migrate users from a Drupal 5 site to a Drupal 7 site.
I installed the Migrate and Drupal-to-Drupal data migration modules. I know I have to make a custom module extending the built in classes of migrate_d2d module to migrate users.
Which migration class should I extend while making the custom class? Is it correct that the custom class should be placed in the user.inc file?
