When a customer purchases VCF, VVF they receive a vSphere key and a vCenter key. The vSphere key acts as a Solution Key, which unlocks all features when assigned to vCenter; however, to unlock the features, vCenter must be on version 8.0U2b or higher. If for any reason a customer cannot upgrade their vCenter, they can use the vCenter key instead.
For more information on VCF Solution license key that will unlock the product features, Refer: VCF VMware Cloud Foundation and vSphere Foundation Solution License Key
