Administrators need to have a sense of all of the subscriptions attached for their account, altogether, regardless of whether the system is managed in RHN Classic or Customer Portal Subscription Management. The Customer Portal provides a way of looking at the total attached subscriptions.
In the Subscriptions Overview page, the Subscription Utilization area at the top gives the current count for every active subscription for the entire account, and a total count of every used subscription, regardless of whether it is used in RHN Classic or Customer Portal Subscription Management. These numbers are updated whenever the subscription count changes in the subscription server.

RHN Classic is intended to be used with legacy systems (Red Hat Enterprise Linux 6.0 or Red Hat Enterprise Linux 5.6 and earlier releases). It is strongly recommended that Red Hat Enterprise Linux 6.1/5.7 and later systems use Customer Portal Subscription Management, Subscription Asset Manager, or other certificate-based subscription management service.
