This illustration shows the four phases of the Wireless out-of-place upgrade. The Wireless component uses the Oracle RDBMS, while other iAS components use the Infrastructure metadata repository. In the first phase, iAS 1.0.2.2.x is shown accessing the Oracle RDBMS. Second, iAS 1.0.2.2.x is shown accessing the Oracle RDBMS, with an adjacent iAS 9.0.2.0.x installation accessing the metadata repository. Third, the Wireless data is migrated from the Oracle RDBMS to the metadata repository, where it is accessible from the 9.0.2.0.x installation. Fourth, the 1.0.2.2.x installation is decommissioned.
