Before you upgrade or migrate to the latest release of Oracle Analytics Server, learn about upgrade and migration.

Oracle has introduced many enhancements to existing features in Oracle Analytics Server. Sometimes, these enhancements replace the existing functionality or reimplement it in a different way. Wherever possible, the existing prior release functionality and configuration is migrated to the corresponding Oracle Analytics Server system. Although the appearance and behavior of the Oracle Analytics Server system can be different, the end result is expected to be functionally equivalent.

An efficient upgrade or migration strategy allows you to migrate your metadata and configuration from your Oracle Business Intelligence environment. The goal of this process is to not exactly replicate the appearance and behavior of the original Oracle Business Intelligence system in the latest Oracle Analytics Server environment. Replicating the Oracle Business Intelligence appearance and behavior is time-consuming and sometimes difficult, if not impossible. For example, the dashboards and prompts are represented differently in Oracle Analytics Server and would require significant manual intervention to recreate the Oracle Business Intelligence appearance. It also undermines the rationale behind moving on to Oracle Analytics Server; namely, to take advantage of the enhancements that are introduced in Oracle Analytics Server.
