Changing a node alias to reuse his old url programmatically without be still redirected to the node page

Question

I'm on a old site on drupal 7. I have a node with alias /url. Now I need to manage that page url programmatically, so I create an item in a custom module using hook_menu() in this way:

/**
 * Implements hook_menu().
 */
function MYMODULE_menu() {
  $items = [];

  $items['url'] = [
    'title' => 'New Title',
    'page callback' => 'MYMODULE_url_callback',
    'access callback' => TRUE,
    'type' => MENU_CALLBACK,
  ];

  return $items;
}

In the previous node I've changed the alias to /url-old but when I go to the page /url I've been redirected to /url-old and can't reach the new page.

Where is still referenced the relation between node/<nid> and his old alias /url?

I've the module Pathauto installed. In the aliases list the /url link is no more present.

Thanks in advance.

Answer 1

I've found where are defined all node's redirects:

Configuration > Search and metadata > URL aliases.

Needs to remove all occurrence for the new url before to reach the page programmatically.
