Upgrading Kerio Connect to the Latest Version

Overview

Kerio Connect can be upgraded automatically or manually.

• If an automatic upgrade is enabled and functions correctly, all the latest releases of the product (including the new features/functionalities and fixes) are received without any manual intervention.
• In case the automatic upgrade fails, or it is not available, check for a manual upgrade to keep your Kerio Connect updated.

This article shares the processes for configuring the server to upgrade Kerio Connect automatically or manually by covering the following topics:

• Prerequisites/Considerations for Upgrading
• Configuring Server to Check for Updates
  • Setting up Proxy Server
• Upgrading Kerio Connect Automatically
• Upgrading Kerio Connect Manually
• Troubleshooting Upgrading Issues

Prerequisites/Considerations for Upgrading

• Take a full back up of Kerio Connect.
• Verify that your software maintenance agreement is valid.
  
  Note: The software maintenance agreement expiration date can be found on the splash screen of the Kerio Connect administration console. Users are entitled to upgrade to the latest version that is released during their software maintenance period, even after the agreement's expiration.
  
  For example, if the latest version was released last week and your maintenance agreement expires today, you will be able to upgrade to this latest version tomorrow.
• When performing a manual upgrade to Kerio Connect 9.2.7 and above on Linux, first install the cryptsetup package before attempting to upgrade. When you are using the administration interface for the upgrade, this package installs automatically.
  

  Note: You must have SuperUser/root privileges to upgrade Kerio Connect on Linux systems manually.

• Make sure that your server meets the required system and hardware requirements.
• Kerio Connect requires a restart during the upgrade. Therefore, it is best to perform the upgrade when there is no traffic on the server or when it is least impacting on your business operations.
