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, i.e. 9.3.0 is available.
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
- 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.
Go to Configuration > Advanced Options.
Click on the Software Updates tab.
Select the Automatically check for new versions option. If you are using Kerio Connect in production, do not enable the Check also for beta versions option.
Click Check now.
- Then a new version is being downloaded and the Kerio Connect server is being upgraded.
- Once the upgrade is finished, the informational success window is displayed.
Setting up Proxy Server
Optionally, follow these steps to set up a proxy server for updates:
Go to Configuration > Advanced Options.
Switch to the HTTP Proxy tab.
Select the Use HTTP proxy for antivirus updates, Kerio update checker and other web services option.
Enter the Address of the proxy server.
Enter the Port of the proxy server.
If the proxy server requires authentication, enter its username and password.
Notifications about the new version
If you are using Kerio Connect 9.2.5 and above, you can automatically upgrade the Kerio Connect by navigating to the Configuration > Advanced Options > Software Updates tab in the administration interface.
- If a new version is available, Kerio Connect displays a notification on the dashboard.
- Similarly, you can also find this information in the Advanced Options > Server Updates section.

Depending on your platform, follow the instructions given below:
