Upgrading Veeam Backup Enterprise Manager in Silent Mode

You can upgrade Veeam Backup Enterprise Manager in the silent mode with a special XML answer file by using the command line interface. The answer file contains all the necessary upgrade settings in the proper order and their thorough description.

Before You Begin

Before starting the upgrade of Veeam Backup Enterprise Manager in the silent mode, consider the following:

The user account that you use to run the silent upgrade must be in the local Administrators group on the machine where the silent upgrade will run. The silent upgrade cannot be run under the LocalSystem and NetworkService accounts.
If the user account that you use to run the silent upgrade is logged on the machine using the network logon method, the silent installation will fail. To avoid this, use an additional /SkipNetworkLogonErrors command line key. For example, it is required when the silent installation is started using a remote PowerShell session.
When configuring the answer file, remove or comment out unused [Optional] parameters. Otherwise, the upgrade session will fail.

Upgrading Veeam Backup Enterprise Manager

To upgrade Veeam Backup Enterprise Manager in the silent mode, take the following steps:

Copy the EmAnswerFile_upgrade.xml file to your local drive.

You can find the template answer file on the Veeam Backup & Replication installation disk in the \Setup\Silent\AnswerFiles\EM folder.

Configure installation parameters according to your needs. For details, see Configuration Parameters.

Check that the answer file has the correct bundle (Em) and mode (upgrade) specified in line 2:

After you make all the necessary changes in your answer file, start the upgrade by running the Veeam.Silent.Install.exe file located on the Veeam Backup Enterprise Manager installation disk in the \Setup\Silent folder. Use the following command line keys in your command:

D:\Setup\Silent\Veeam.Silent.Install.exe /AnswerFile E:\MyAnswerFileEMUpgrade.xml /SkipNetworkLogonErrors

where:

/AnswerFile — required key for specifying the path to your custom answer file, for example: E:\MyAnswerFileEMUpgrade.xml.
/SkipNetworkLogonErrors — optional key that allows skipping additional pre-installation validations that do not work under the network logon, which will block the silent installation from running.
/LogFolder — optional key for specifying the path where the setup should save log files if it is different from the default path. The default path is: C:\ProgramData\Veeam\Setup\Temp.
