Explanation
Data integration technologies such as Oracle GoldenGate or Oracle Data Integrator can be used to migrate, and if necessary transform data. Typically, such environments provide a high degree of flexibility, along with a productive way of defining and implementing the required data integrations and transformations. Also, these technologies are often used to facilitate data migration while the source system continues to run. If your application service-level agreements permit little or no down time, you can use an Oracle Data Guard logical standby database to replicate the database on Database Machine, and track and merge the changes while the source database continues to run.
