This section provides the information you need if you are upgrading from the Identity Manager Fan-Out driver to the Identity Manager 4.0.1 driver for IBM i (i5/OS and OS/400).
Topics include
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 IBM i 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 i and z/OS* systems. The Fan-Out driver also provides authentication redirection from those systems.
Moving to the IBM i driver provides two main advantages.
Bidirectional Synchronization: The IBM i driver allows synchronization from the connected IBM i 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 IBM i driver.
Heterogeneity: The Fan-Out driver supports operating systems in addition to IBM i. You can continue to use the Fan-Out driver for those systems while using the IBM i driver for IBM i systems.
Scalability: The Fan-Out driver can fan out identities to any number of systems. The IBM i driver can replicate to only one system.
One IBM i driver is required for each connected system. For best performance, we recommend no more than a total of 60 drivers.
Authentication Redirection: The Fan-Out driver uses authentication redirection from IBM i using the Change Password Validation Program exit. The IBM i driver uses bidirectional password synchronization.
