Overview

This article applies for Kerio Connect version 9 and higher (9.2.x, 9.3.x, 9.4.x, 10.x.x). As long as you are already on version 9 (or higher), a direct upgrade can be performed from your current version to the latest one (including Kerio Connect 10). If you are on an older version, please follow the steps for Upgrading Kerio Connect older than Version 9.0.0.

Kerio Connect can be upgraded automatically or manually. If an automatic check for update/upgrade is enabled and functions correctly, the new version will be detected automatically.

In case the automatic upgrade fails, or it is not available, perform a manual upgrade procedure 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 and Considerations for Upgrading
• Automatic Upgrade
  • Setting up Proxy Server
• Notifications about the new version
• Upgrading Kerio Connect Manually
• Troubleshooting Upgrading Issues

Prerequisites and Considerations for Upgrading

• Take a full backup 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.
• If using Kerio Connect on a macOS, if the server fails to start after upgrading, make sure that the mailserver process has Full Disk Access (To check that, you can follow the steps outlined in Unable to use External backup Volumes in macOS).
