Most agents in the Policy Agent 2.2 release are compatible with Access Manager 6.3 Patch 1 forward.
Moreover, all the 2.2 agents are compatible to some degree with Access Manager 7.0 and Access Manager 7.1. This compatibility applies to both of the available modes of Access Manager: Realm Mode and Legacy Mode.
However, when Agent for Microsoft IIS 6.0 is deployed to protect Microsoft Office SharePoint 2007 or Outlook Web Access 2007, Access Manager 6.3 is not supported and not all the specific patch versions of Access Manager 7.0 and Access Manager 7.1 are supported. See the patch compatibility list that follows.
The best practice is to install the latest Access Manager patches to ensure that all enhancements and fixes are applied.
Access Manager 6.3 from Patch 1 forward
However, certain limitations apply. For more information about the limitations, see Backward Compatibility With Access Manager 6.3
