While you aren’t able to upgrade from the standard physical edition, you should be able to upgrade if you bought the standard digital edition to the Digital Deluxe or Ultimate Edition. You can also upgrade from the Digital Deluxe to the Ultimate Edition.
In order to upgrade the digital editions of Diablo IV, you have to do so by using Platinum from the in-game store. You won’t be able to upgrade from the PlayStation Store, Xbox Store or Steam. Instead, you can buy Platinum from these platform stores and then spend the Platinum to purchase your upgrade from the in-game store of Diablo 4.
