Taxonomy migrations are not recognized when this module is enabled

The module alters migrations using the d7_taxonomy_term source plugin. The new source plugin d7_taxonomy_machine_name_term expects the taxonomy_machine_name module to be enabled on the source site.

If you are using the taxonomy_machine_name in Drupal 10/11, but did not use it in Drupal 7, then the migrate system will disable/remove taxonomy term migrations because their source plugin requirement is not met. That is, taxonomy_machine_name is not enabled in the source site.

One way around this is removing this module's hook_migration_plugins_alter implementation like this:

/**
 * Implements hook_module_implements_alter().
 */
function UDRUPAL_COM_module_implements_alter(&$implementations, $hook) {
  if ($hook == 'migration_plugins_alter') {
    // Disable taxonomy_machine_name_migration_plugins_alter().
    unset($implementations['taxonomy_machine_name']);
  }
}

Replace UDRUPAL_COM with your custom module's name.

@dinarcon Thank you for the clarification, I will give that a try.
