Cross-platform migrations are currently not supported. For example, it is not possible to migrate from Access Manager installed in a SLES environment to a Windows environment and vice versa.
NetIQ Access Manager Appliance (single-box solution) deployment is supported only for new installations. You cannot migrate from Access Manager 3.1 SP4 to Access Manager Appliance 3.2.
Migration from the Access Gateway Appliance to the Access Gateway Service and vice versa is not supported.
Cookie mangling should not be enabled in the mixed-mode cluster. The 3.1 SP4 Access Gateways do not understand mangled cookies.
