Overview

The purpose of this article is to provide information about the upgrade paths and describe the required steps as to how to download the latest build and upgrade GFI LanGuard to the latest version.

Information

Since updated definitions are provided only to the latest version, we recommend upgrading your LanGuard considering the upgrade paths below.

Backup LanGuard

It is recommended to back up your current GFI LanGuard database, and the GFI LanGuard Data directory, and export the GFI LanGuard settings before an upgrade, as described in Backing Up GFI LanGuard. This backup may be useful in case the upgrade fails.

Upgrade Procedure

Once ready, proceed with the upgrade steps below:

1. Log on to your current GFI LanGuard server as an Administrator or use an account with administrative privileges.

2. Download the Upgrade on the server where GFI LanGuard is currently installed. 

3. Right-click the newly downloaded installer and choose Properties.

4. From the General tab, click Unblock and then Apply. This step is required to prevent the operating system from blocking certain actions by the installer.

5. Disable anti-virus software on the server machine during the upgrade installation. Re-enable it once the upgrade is complete.

6. Launch the installer.

7. The wizard prompts you to choose an existing Microsoft SQL Server or SQL Express. 

8. Follow the wizard steps to install the new version 

Note: Agents normally will be updated at the start of the next agent scanning operation, but it will require some time to be completed.
