Signature pack exceeds maximum filesize

New Contributor II

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 (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)

First thing, you must upgrade from 3.6.1 to latest 3.6.2, and than upgrade to 5.2.x.

second, I suppose mentioned remark is valid when you upgrade from 5.0 to 5.2, as 3.6 has different signature file format and size...

I can see that 5.2.2 wants a minimum of 3.6.2 (and I'm not going to upgrade straight to a just-released-yesterday version!), but the upgrade guide for 5.2.1 states:

"Upgrade from SZ versions 3.6.0, 3.6.1, 3.6.2, 5.1.0, 5.1.1, 5.1.2, 5.2.1 directly to 5.2 is supported."

Hi Steve,

You can upgrade to 5.2.1 directly from 3.6.1.

Make sure image size and image MD5 is matching before you upload and apply.

I'm having the same issue trying to upgrade from to, when I try to upload the SigPack it shows 'The file size (9.7MB) cannot exceed the maximum size (2.0MB)'.

Is there any solution to this?

Best regards,
