You can configure a connection and mapping in one environment and then migrate and run the mapping in another environment.
After the migration, you can change the connection properties from the Administrator service, but you do not need to modify the mapping. Data Integration uses the configured runtime attributes from the earlier environment to run the mapping successfully in the new environment. The migrated mapping uses the same bucket configured in the connection properties.
Consider a scenario where you develop a mapping in the development organization and you then migrate and run the mapping in the production organization. After you migrate, you might want to use the same or a different connection endpoint in the production organization.
