If you choose to distribute individual access keys to end users, then you will be assigning an access key to each end user's machine. Should the end user need to upgrade their machine, they can re-use the same access key for the new machine. There is a limit on how often a machine can be changed. This frequency is limited to 45 days by default, but it can be changed for each deployment pool per request to Accusoft Corporation.
If you choose to acquire access keys automatically, then you will need to use the LicenseInfo API of the Licensing Component to help end users transfer their access keys into new hardware. For example, you might want to develop a license transfer utility or provide this functionality from within your application. This will allow the end users to extract the access key (that was automatically obtained) from the registry on the old machine and store it onto the new machine. The limitation on the frequency of hardware upgrades applies to this method as well.
