3.1 Upgrading

An upgrade is when you install the new version of Identity Manager on the existing server. To install Identity Manager, you must upgrade the current versions of the operating system and eDirectory to the supported versions for Identity Manager 4.0.2. For a list of the supported platforms, see System Requirements in the Identity Manager 4.0.2 Framework Installation Guide.

The are several advantages to performing an upgrade:

There are also disadvantages to performing an upgrade:

There are certain scenarios when an upgrade is not feasible, or when multiple upgrades must be performed. Because Identity Manager 3.5.x and later are the only supported migration paths, these are the only versions that are described in the following scenarios.

The only supported situation for an upgrade is to have Identity Manager 3.5.x or Identity Manager 3.6.x on a supported operating system. However, there are some scenarios where an upgrade is not feasible. The following are some examples:

If you are performing an upgrade, proceed to Section 4.0, Performing an Upgrade.

IMPORTANT:If Identity Manager 3.6.x is installed into an existing RBPM 3.7 system, the 3.6.1 Roles driver (which was launched automatically and silently by the Identity Manager 3.6.x installer) causes the nrfLocalizedNames and nrfLocalizedDescrs attributes setting to change from case‐ignore string to case‐exact string and overwrites the objects that result in a non‐functional RBPM 3.7 system. For the system to work, ensure that you use the back-up of the driver that was created, before Identity Manager 3.6.x installer is invoked again.
