Migrating metadata and configuration from an existing Oracle BI 11g system requires time and resources. A poorly optimized 11g deployment can disrupt the migration process and can affect the performance of the 12c system. Oracle recommends that you analyze and optimize the existing 11g system by removing redundant content and merging and consolidating similar content.
When you analyze the existing 11g system, note the current hardware and operating system environment on which it is running. Compare the current environment with the Oracle Fusion Middleware 12c system requirements and certification information. There is a set of new system requirements for deploying Oracle BI 12c. For example, Oracle BI 12c requires a newer version of the operating system and a newer version of Java JDK. For more information, see:
The system requirements document at Oracle® Fusion Middleware System Requirements and Specifications
The certification document at Oracle Fusion Middleware Supported System Configurations
While analyzing the 11g system, note the following details:
To optimize the existing 11g system in readiness for migration, perform the following tasks:
