Note
: The
CA Single Sign-On
12.7 documentation does not contain information on upgrading from Release 12.0 to Release 12.7 as
CA Single Sign-On
12.0 has reached its End of Service before the release of
CA Single Sign-On
12.7. However, several customers could successfully upgrade from Release 12.0 to Release 12.7 using the Release 12.6.01 upgrade information. If you are using Release 12.0 that has an extended support contract and would like to upgrade to Release 12.7, contact CA Support for assistance that is consistent with your extended support contract.
Before you begin a parallel upgrade, review the following information:
Parallel Upgrade Overview
The following figure illustrates a simple parallel upgrade with the following details:
  • An existing environment that continues to protect existing resources.
  • An existing Administrative UI that manages objects in the policy store.
  • A new environment that protects new resources.
  • A new Administrative UI that manages objects in the new policy store.
  • A common key store. The common key store enables single sign-on between both environments.
Though not illustrated, you can enable single sign-on between both environments using multiple key stores.
