Supported Upgrade Paths

An upgrade consists of deploying r12.5 components to an existing SiteMinder environment. Upgrading to r12.5 can be accomplished in two ways:

Completing a migration.
Configuring a parallel r12.5 environment next to an existing environment. Both environments use one or more key stores to maintain single sign–on.

If you are upgrading from r6.x, both upgrade paths are supported.
