Why is Classic MetaLink being retired?

Oracle has acquired 50+ companies in the past 5 years. In order to provide a common, consistent support experience we are in the process of moving all of our customers onto a single, integrated support platform, My Oracle Support. As we integrate our support portals, we are also investing in a support solution that provides many more value-added capabilities than are available in the current version of Classic MetaLink.  My Oracle Support provides you with personalized, proactive, and collaborative support capabilities that help reduce the time you spend maintaining Oracle solutions.
My Oracle Support is tightly coupled with the Configuration Manager to help users achieve problem avoidance and faster problem resolution. When activated, the Configuration Manager provides Oracle with system configuration details that help accelerate problem resolution time and improve system stability.  With My Oracle Support users get features unavailable on Classic MetaLink such as Healthchecks, Patch Advice, and proactive security and product alerts.
