An upgrade is available from GFI LanGuard 12.4 to
GFI LanGuard 12.11

Follow these notes and instructions to upgrade your current GFI LanGuard installation to the latest version while retaining all settings.

GFI LanGuard 12.2 supports TLS 1.1. If you plan to deploy GFI LanGuard in an environment where TLS 1.1 and above is running, you need to enable FIPS-Compliant algorithms on the local policy. For more information refer to GFI LanGuard and TLS 1.1 or higher.

Ensure your server meets the system requirements.
Backup your current GFI LanGuard database and the GFI LanGuard Data directory which is typically available from: C:\ProgramData\GFI\LanGuard <version>\
Export the GFI LanGuard settings before upgrade. This backup may be useful in case the upgrade fails. For more information refer to Importing and exporting GFI LanGuard settings.
Log on to your current GFI LanGuard server as an Administrator or use an account with administrative privileges.
Save any pending work and close all open applications on the machine before starting the upgrade.
Disable anti-virus software on the server machine during the upgrade installation. Re-enable it once upgrade is complete.
