update_prepare_d7_bootstrap()

Users who still have a Drupal 6 database (and are in the process of updating to Drupal 7) need extra help before a full bootstrap can be achieved. This function does the necessary preliminary work that allows the bootstrap to be successful.

No access check has been performed when this function is called, so no changes to the database should be made here.

includes/update.inc, line 68

  // Allow the bootstrap to proceed even if a Drupal 6 settings.php file is
  // still being used.
