Hello everyone,I am planning a firmware upgrade for a FortiSandbox currently running 4.0.9. My target is 4.4.9.Since this is a jump across several versions, I'm looking for a validated Method of Procedure (MOP). Specifically: Upgrade Path: Based on the release notes, is a direct jump supported, or do I need to step through 4.2.x first? Cluster Impact (If applicable): If I'm in a Primary/Worker setup, should I expect significant downtime for the Rating Engine sync between these versions? Are there any known issues in the target versions that needed to consider? If anyone has a step-by-step checklist or "gotchas" for this specific path, I’d appreciate the help!

FortiSandbox Firmware Upgrade

Hello everyone,

I am planning a firmware upgrade for a FortiSandbox currently running 4.0.9. My target is 4.4.9.

Since this is a jump across several versions, I'm looking for a validated Method of Procedure (MOP). Specifically:

Upgrade Path: Based on the release notes, is a direct jump supported, or do I need to step through 4.2.x first?
Cluster Impact (If applicable): If I'm in a Primary/Worker setup, should I expect significant downtime for the Rating Engine sync between these versions?
Are there any known issues in the target versions that needed to consider?

If anyone has a step-by-step checklist or "gotchas" for this specific path, I’d appreciate the help!

Hi defs defs

Are you sure you have 4.0.9?

I can’t find this version anywhere on the support portal neither in release notes.
