K1000 - What controls the downgrade rights calculation
In summary, software downgrade and upgrade rights rolls up to product or product+edition (for same product and edition). By default, Downgrade rights will downgrade to all older versions of the software. Upgrade rights will upgrade to next higher version of the software. With K1 7.0, there are additional options to manage software upgrade and downgrade rights. This allows customers to control the behavior and accurately manage complex upgrade/downgrade scenarios such as Windows. Users can select specific software items from the list to downgrade or upgrade.
Under the default behavior, the process will capture the available licenses and use it for same version to meet the compliance need and then sum up all leftover (unused) licenses for downgrade rights that can be allocated and then allocate as necessary for lower versions. The order of operation should be descending. The reason for this logic is many publishers allow downgrades to only one version below. For some publishers it does not matter as one them will be out of compliance.
