If you are updating from any version 9 or below start reading here:
Server Manager has changed: Instead of being a pop-out configuration dialog, Server Manager has now been fully integrated into the user interface in a much more user-friendly format. For reference, please see: Server Management
If you are updating from version 10 or below...:
User Manager has changed: Instead of being a pop-out configuration dialog, User Manager has now been fully integrated into the user interface in a much more user-friendly format. For reference, please see: User Management
If you are updating from version 12.2.2 or below...:
There are now service account options in the Installer: When you run the installer, you will now see several options regarding the service account running Cerberus. You can select the 'Use Current' configuration (recommended for the least disruption). If you are using 'Local System' to run Cerberus and you select this, the install will continue. If you already have a dedicated service account running Cerberus and select this option, you will be prompted for the password.
The next option is to have Cerberus create a dedicated Standard Service Account, which will be a new local user account on the server. You also have the option to switch to an existing Local Account or existing Service account. In both these cases, a username and password will need to be provided.
You can verify what service account option you are using by checking 'services.msc'. Right-click on 'Cerberus FTP Server' and 'Properties', then the 'Log On' tab. You'll either see 'Local System' or see custom credentials specified.
While moving away from ‘LocalSystem’ is the right choice, in the long run, please be aware that a change to service credentials should be tested thoroughly before being applied to production environments.
You must ensure the new service account has privileges on all virtual directory paths used by Cerberus FTP Server. Files referenced in configuration, like certificates and private key files must also be accessible. When moving to a domain service account, you must also ensure the account has read-access to all users and groups integrated with Cerberus FTP Server. Finally, the account must be able to read and write to all the settings files in C:\ProgramData\Cerberus LLC\Cerberus FTP Server.
By default, Cerberus used to revert back to using 'Local System' when updating and customers using custom service accounts had to restore the credentials before restarting the service. With these new updater options, this will no longer be the case.
If you are updating from version 12.3.4 or below...:
The Cerberus desktop User Interface now uses Microsoft WebView2 to render the UI pages, instead of Internet Explorer:
This is a Microsoft Edge (Chromium) platform that allows developers to bring web experiences into native apps. Cerberus has moved to this platform to display desktop user interface pages instead of relying on Internet Explorer. This is to modernize the Cerberus user interface and also improve performance.
While it is NOT required as the Cerberus user interface will continue to use Internet Explorer if you don't install WebView2, we recommend WebView2 as it significantly improves UI performance.
The installer will attempt to download and install this platform if it detects it is not installed. To reduce the possibility of an issue when updating, it is possible to do a manual install of WebView2 BEFORE updating Cerberus. That way Cerberus won't try to install it when you update.
Here is the Microsoft page describing WebView2 which also has install links.
It is recommended that you use the 'x64' link in the 'Evergreen Standalone Installer'. Optionally you can download the 'Evergreen Bootstrapper' which is a tiny installer that downloads the Evergreen Runtime matching device architecture and installs it locally. There is also a link that allows you to programmatically download the Bootstrapper.
Steps to update:
DO NOT use the auto-updater! You will encounter issues updating from version 10 or below if you use it.
Manually download and run the latest Installer
Manually download the latest installer. The installer will upgrade an existing installation to the latest release. To download and run the latest installer:
- Go to the Cerberus Download page
- Download the latest installer. (Please note that as of Cerberus version 12, a 32-bit version is no longer available or supported)
- Shut down the Cerberus FTP Server UI. Go to the File menu and select the Exit menu option. DO NOT use the 'red X' on the upper right! You should also shut down the Cerberus FTP Server Window Service. The installer will normally be able to shut down the service, but on rare occasions, the automatic shutdown will not work. Shutting down the Cerberus Windows Service before installation ensures an error-free installation and that all your users and settings are preserved.
- Launch the installer. You should select the default options for any questions in the installer (See notes about the installer enhancements above). The installer will automatically remove your existing installation and install the latest release. All of your existing users and settings will be preserved.
- Finish the installation and you are done. The latest version of Cerberus FTP Server should now be installed and running.
You should expect only about a 5 minute actual interruption of the service.
