Oracle Database Migration
Migration is the process of moving data from one database to another with changes in hardware, software, storage types, and so on. It is kind of like introducing your data to a new system. In Chapter 2 we discussed database upgrades where you just upgrade your database to a higher version, with no changes in hardware or the underlying platform. But that is not always the situation; besides upgrading, you may need to move to a different environment. This migration could be because of business needs such as mergers or acquisitions, to improve performance, or to reduce the cost or requirements of the application. Fortunately, Oracle has provided a rich set of tools and utilities for moving data across systems. This chapter gives you an overview of the different migration options provided by Oracle.
