Why to upgrade to 12c
2 likes276 views
This document discusses the benefits of upgrading to Oracle Database 12c. It highlights features like improved provisioning capabilities, better support for cloud environments, enhanced scalability through policies and server pools, data movement and consolidation improvements, in-memory processing, high availability, simplified upgrades and migrations, cost savings, and predictive management tasks. Upgrading is recommended to benefit from these features and because Oracle support for 11g will end soon.
