Maintain Session Stores for Single Sign-on in a Mixed Environment

You can share a common session store between a 5.5 and r6.0 SP6 Policy Server to maintain single sign-on (SSO) if:

• The session store remains at 5.5.
• All Policy Servers point to the 5.5 session store.

Note: This configuration is not recommended in a 6.x Federation environment. Some of the advanced Federation 6.x features are not supported with this configuration.
