I want to make sure I'm up to date with the OS version on my SA but I'm not sure whether I can safely apply the latest 6.4. On the outsdie of the box it says it's a netscreen SA 1000 but in the admin console under platform is clearly says it's SA-2000 and again in licensing??? Does this mean I can continue to apply more recent updates than 6.0R3.1 or am I stuck at this level now for SA 1000? Thanks James ... View more
