Premigration Steps > Choosing a Migration Strategy

Choosing a Migration Strategy

Once the right information is gathered from the current source systems in the discovery sessions, the appropriate migration strategy can be chosen. Typically in a situation dealing with large and complex database migrations, a single migration strategy may not be the best option, but rather a combination of multiple strategies that best suits the specific platform being migrated should be considered.

The following sections discuss a variety of database platform migration strategies that can be used in real-world migration projects.

Replatform with Refactoring Strategy

A replatform migration approach for databases is usually focused on replacing the existing database server platform with a bigger and faster platform like the Exadata Database Machine. This replacement is done while keeping the surrounding applications and their interfaces with the database system intact. In a replatform of non-Oracle databases to the Database Machine, the legacy database software will be replaced with the Oracle Database software.
