Downgrading License Keys
If you have license keys for vSphere 5.0, but you need to license VMware Infrastructure 3 or vSphere 4.x assets, use the license portal to downgrade the license keys. When you downgrade the license keys, the vSphere 5.0 license keys remain valid. When you are ready to upgrade your assets, you can stop using the VMware Infrastructure or vSphere 4.x licenses and start using the vSphere 5.0 license keys by adding them to the vCenter Server license inventory and assigning them to your upgraded assets.
Combining the Capacity of License Keys
Combining license keys is useful when the total available capacity across license keys is large enough to accommodate an asset, but no single license key is large enough to accommodate the asset.
After you use the license portal to combine license keys, you must add the new license key to the vCenter Server license inventory and remove the old license keys.
Dividing the Capacity of License Keys
If you have a large-capacity license key, you might want to divide the capacity to create multiple smaller capacity license keys.
Dividing license keys is useful for managing license keys in different vCenter Server license inventories or assigning different license keys to groups in your organization.
