Upgrading from GFI LanGuard 12.1 or later
This topic describes how to upgrade a GFI LanGuard version 12.1 or later installation to the latest version while retaining all settings.
Important notes before upgrading
- 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.
