Parallel Upgrade

A parallel upgrade is the process of configuring an r12.5 environment next to an existing environment. Configuring a parallel upgrade consists of multiple steps during which you:

• Leave the existing environment unchanged.
• Configure an r12.5 environment.
• Use a common key store or multiple key stores to enable single sign–on between both environments.

The following diagram illustrates the concept of a parallel upgrade. For more information about completing a parallel upgrade from r6.x or r12.x, see the respective chapter.
