This section provides the information you need if you are upgrading from the Identity Manager Fan-Out driver to the Identity Manager 3.5.1 driver for i5/OS (OS/400).
We recommend that you perform the upgrade in a test environment similar to your production environment before upgrading production systems.
Before beginning the upgrade process, review Section 3.0, Installing the i5/OS (OS/400) Driver.
To prepare for installing the upgrade:
Verify that you have the required knowledge and skills.
For details, see Section 3.2, Required Knowledge and Skills.
Ensure that the prerequisites are met.
For details, see Section 3.3, Prerequisites.
Prepare the distribution files for installation.
For details, see Section 3.4, Getting the Installation Files.
The Fan-Out driver provides one-way synchronization to a heterogeneous mix of systems including Linux* and UNIX* systems, and IBM OS/400 and z/OS* systems. The Fan-Out driver also provides authentication redirection from those systems.
Moving to the i5/OS driver provides two main advantages.
Bidirectional Synchronization: The i5/OS driver allows synchronization from the connected i5/OS system.
Standard Identity Manager Policies That Simplify Customization: The Fan-Out driver makes minimal use of Identity Manager policies.
Consider the following before migrating from the Fan-Out driver to the i5/OS driver.
Heterogeneity: The Fan-Out driver supports operating systems in addition to i5/OS. You can continue to use the Fan-Out driver for those systems while using the i5/OS driver for i5/OS systems.
Scalability: The Fan-Out driver can fan out identities to any number of systems. The i5/OS driver can replicate to only one system.
One i5/OS driver is required for each connected OS/400 or i5/OS system. For best performance, we recommend no more than a total of 60 drivers.
Authentication Redirection: The Fan-Out driver uses authentication redirection from OS/400 using the Change Password Validation Program exit. The i5/OS driver uses bidirectional password synchronization.
