I am not sure they will give you the validation code for the 14 years old license. You may install the trial license of QBD 2011, 2015, 2019 and 2021 to upgrade your old file in stages. Then you may purchase a one time license of QBD 2021 Pro 1 user worth $299 or Premier 1 user worth $499 later. We may share the trial codes of them all. Otherwise, you may purchase a 3rd party upgrade service.
