Policy Agent 2.2 is backward compatible with Access Manager 6.3 Patch 1 or greater.
Policy Agent 2.2 is only compatible with Access Manager 6.3 when the Access Manager patch has been applied.
By default, J2EE agents in the Policy Agent 2.2 release work with Access Manager 7. While the 2.2 release of Policy Agent requires some configuration to work with Access Manager 6.3 Patch 1 or greater, the amount of configuration required is relatively limited. For more information, see Configuring A J2EE Agent With Access Manager 6.3.
Be aware that Policy Agent 2.2 takes advantage of certain features that exist in Access Manager 7 that do not exist in Access Manager 6.3, such as “composite advices,” “policy-based response attributes, ”and others.
