I'm preparing to upgrade our SZ100 from 3.6.1 to 5.2.1 which appears to be a supported upgrade path according to the upgrade guide.
Instructions on the 5.2.1 download page say: "Before upgrading SZ100 to 5.2.1.0.515 (GA), update to the Application Recognition and Control v1.470.1 signature package file"
However, if I try to install that signature package to the current system, it errors with 'The file size (9.7MB) cannot exceed the maximum size (2.0MB)
I can't see any file size settings, so presumably it's a hard coded limit. So how do I install the signature pack before I upgrade the firmware? Can I ignore that and install the signature pack afterwards? The upgrade guide suggests not.
Do I need to go through any interim versions, and if so which ones? (again, upgrade guide says direct upgrade from 3.6.1 to 5.2 is supported)
