Overview

When your original hardware device is broken or you want to upgrade your infrastructure with a new Kerio Control hardware devices, it's needed to replace the hardware boxes.

To switch from one Kerio Control hardware appliance to another, you need to configure and register the new Kerio Control and then switch off the original appliance.

If your original hardware appliance is still running, configure the new hardware appliance in advance in your office. If the original Kerio Control is broken, you can configure the new one in the production environment.

This article describes the hardware device replacement process.

1. Get the configuration files from the original Kerio Control installation or a saved backup.
2. Connect the new appliance to the Internet.
3. Activate the license.
4. Upgrade the new appliance to the latest version of Kerio Control.
5. Import the configuration to the new appliance.
6. Replace the hardware appliance.

Prerequisites

In the administration interface for the original hardware appliance, go to the Interfaces section and note all the interfaces and their type. You must ensure that the new hardware appliance has the same number of interfaces as the original.

IP addresses assigned to interfaces are imported to the new hardware appliance only if they are in manual configuration mode.

All interfaces with automatic mode get the new IP addresses from the DHCP server. This can be changed later in the Interfaces section.

Information

Exporting a configuration from the original Kerio Control appliance

Access Kerio Control administration and Export your configuration using Configuration Assistant wizard.

For more information, please refer to Exporting and Importing configuration backups.

Downloading a backup from FTP or MyKerio

If your original Kerio Control does not work, download the last backup from the FTP server or MyKerio.

Important: If your original Kerio Control does not work and you don't have a backup, configure the new Kerio Control manually from scratch.

Connecting the new Kerio Control to the Internet

The DHCP server in the Kerio Control hardware appliance is enabled by default. For details, see the printed Installation Guide attached to the Kerio Control hardware appliance.

Note: for new NG boxes, there is a QR-code on the shipping box for install instructions.

Requirements:

• The hardware appliance must be plugged into a socket.
• At least one Internet cable must be connected.
• At least one LAN cable must be connected.

At this point, the hardware appliance is running and you can access the Internet from the local network. However, all users connected to the Kerio Control network will see the "License warning: there is no valid license for the product" page every 2 minutes until you activate your Kerio Control.

Registering a new Kerio Control

If the new hardware appliance is of the same type as the original one, you can use the same license. In all other cases, you need a new license. For details, contact your Kerio sales representative.

Registering the new Kerio Control hardware appliance is a part of the Activation Wizard, which appears when you point your browser to https://10.10.10.1/admin.

Note: You can also register your new hardware appliance through MyKerio. For more details, see adding Hardware Box to MyKerio.

Upgrading the new Kerio Control hardware appliance

Before you import the configuration, you must have the same version of Kerio Control that was running on the original appliance (or a newer version) installed on the new hardware appliance.

If there is a new version available, you will receive a red notification "New update is available" in a Dashboard. You can ignore the SSL certificate warnings as SSL certs will be replaced by the old config.

For more information, please refer to Upgrading Kerio Control.

Once the server has restarted your Kerio Control hardware appliance is up to date.

Important: legacy NG boxes (NG100W, NG300W, NG500) are shipped with Kerio Control 9.2.0, so it's obligatory to upgrade the software. New NG boxes (NG110, NG310, NG510/NG511) are shipped with the 9.3.4 version. It's highly recommended to upgrade them to the latest version available.

Importing a configuration to a new Kerio Control

At this point, you can import the Kerio Control configuration:

1. In the Configuration Assistant dialog box, click Import configuration.
   
2. In the Import Configuration wizard, click Upload configuration file.
3. Select the file and click Open.
4. Select Restore from backup to completely replace all the configuration files.
5. Click Next.
6. Kerio Control pairs the imported network interfaces with the real interfaces on the appliance. To change the result:
   1. Double-click the interface you want to change.
   2. In the Select Interface dialog box, double-click the interface you want to pair. From now on, the interface from the original appliance is paired with the new one.
      If you cannot pair the interfaces, edit them later in the Interfaces section of the administration interface.
7. Click Next.
8. Read the notes in the last step of the wizard and click Finish.

Kerio Control imports the configuration and restarts.

The new Kerio Control hardware appliance is now configured and ready to replace the original appliance.

Switching appliances

IMPORTANT: The following procedure requires Kerio Control to be taken offline.

1. Power off the original hardware appliance.
2. Disconnect all the cables.
3. Swap in the new appliance in place of the original one.
4. Connect all the cables.
5. Switch on the new appliance.
6. Open the web interface of the new appliance.
7. Go to the administration interface and in the Interfaces section check to see whether all the interfaces are configured properly. For example, standalone/LAN switch settings are not transferred, so you must set them up manually.

Warning: Connect to the administration interface from the local network (LAN). The Internet interface does not allow access by default.
