Moving wordpress content to another domain

Hi,

I’m moving a wordpress content to another domain. I’ve uploaded all the files and the database backup file but when I go to this page:
https://74.54.217.210/~nataljaz/videoabbondanza.com/wp-login.php

and I insert my login data, wordpress gives an error because the login page is still connected to the other wordpress site https://www.videoregali.com
so of course it’s expecting different login data.

I’ve solved this once before but now I can’t remember how to do it.
Please help.
