How a Parallel Upgrade Works

You do not have to migrate an existing r12.1 SP3 environment to 12.52. Rather, you can configure a parallel 12.52 environment beside an existing deployment.

The following figure illustrates a simple parallel upgrade and details:

• An r12.1 SP3 environment that continues to protect existing resources.
• An r12.1 SP3 Administrative UI that is used to manage CA SiteMinder® objects in the r12.1 SP3 policy store.

  A 12.52 environment that protects new resources.

• A 12.52 Administrative UI that is used to manage CA SiteMinder® objects in the 12.52 policy store.
• A common r12.1 SP3 key store. The common key store enables single sign-on between both environments.

  Note: Although not illustrated, you can enable single sign–on between both environments using multiple key stores.
