To request the Change Registrant during the transfer of a .it domain name, you need to place an order online from the website selecting the Change of Ownership (Change Registrant) option and entering the details of the new owner.

To request the transfer of the domain you must enter the relevant “Authorization
” code in the order form. 

Aruba will send the transfer request to the Registry only once the payment has been received.
Once the transfer has been completed Aruba will send the new Authorization Code of the domain to the new owner.
