Unable to propertly Migrate / Backup my website

Hello, When I created a backup the links are still related to the old one so I always return to the old one once I click anywhere.

Here is what i have done:

– Copy database

– Import database on a new one

– Copy Drupal folders

– Paste drupal folders on a /copy folder

– Change settings.php database name (the password and user are the same because its same server)

Now if i go to /copy folder it work but when I click on any link im redirected to the old page.

Please help me.

Drupal version:
