https://fortinetcloudcse.github.io/Autoscale-Simplified-Template/6_upgrade_fortios/6_2_in_place_upgrade/index.htmlOverview The in-place upgrade updates the launch template AMI and replaces running instances without deploying a parallel environment. The script reads live ASG state from AWS and selects the appropriate path automatically. Warning Cross-major-version upgrades (e.g., 7.4.x → 7.6.x) require Path C — FortiGate native config sync does not work across major versions. Rolling replacement (Path B) alone is not sufficient; a config restore must follow.Hugoen-US
