Hardware upgrade licenses (for Dirac capable devices) are model specific and get tied to the initial device they were purchased for. They are not transferable to another device, not even to another unit of the same model (Exception: hardware failure, read more below).
Transferring or using licenses across multiple devices or models is not supported. For example, if you bought a license for an NAD M10 and are now buying a Denon X3800H, you will need to purchase a new license, as your NAD license is not transferable to the Denon.
In case of hardware failure the following applies:
If you experienced hardware failure and receive a replacement device of the same model, you can request a license transfer to the new unit by creating a ticket here.
The following information has to be included in your request:
The e-mail address associated with the license.
Documentation proving that you have received a replacement device from the reseller or manufacturer. (i.e. service invoice or correspondence with the vendor)
If a manufacturer will not allow a replacement device (due to being outside of the warranty period), we will not allow re-using the same license on a completely new device.
Transfer license to another user
If you are selling your hardware device and the new owner wants to take ownership of the Dirac Live license, see the following help article for in depth instructions: How do I transfer my license to another user?
