This illustration shows two Identity Management instances and a 10.1.3 middle tier. The first step is that a new Identity Management instance is set up. The second step is that OracleAS Single Sign-On and Directory Integration and Provisioning data is exported to the new Identity Management instance. When the first Identity Management instance is unavailable, LDAP-based replication is stopped, the middle-tier instance is associated with a new 10.1.2 Identity Management instance, and the latest copy of the data is imported.
