The Oracle Migration Workbench (Migration Workbench) is a tool that simplifies the process of migrating data and applications from databases other than Oracle. The Migration Workbench allows you to migrate an entire application system (that is, the database schema, including triggers and stored procedures) in an integrated, visual environment. The Migration Workbench is:
The wizards walk you through the entire migration process.
It uses the repository to store migration information. This information is then persistent for the life of the migration and allows you to initially load the database schema into the repository. This permits you to work independently of the production application.
Each plug-in available to you is database specific and extends the Migration Workbench to support the migration of a specific database to Oracle. After installing the Migration Workbench you must then install the plug-in for the database you want to migrate. By default, you download the Migration Workbench without any plug-ins. You can download the appropriate plug-ins from the Oracle Technology Network Web site at:
