# Use silent mode to upgrade

Silent mode installation is a non-graphical method for running the Pentaho Upgrade Installer. In silent mode, no prompts are issued throughout the upgrade process.

Perform the following steps to run the Pentaho Upgrade Installer in silent mode:

1. Exit out of any Pentaho products you are currently running.

   If you are upgrading your Pentaho Server, stop the server. For instructions, see [Start and stop the Pentaho Server for configuration](/install/9.3-install/pentaho-configuration/tasks-to-be-performed-by-an-it-administrator/configure-the-pentaho-server/start-and-stop-the-pentaho-server-for-configuration.md).
2. At the command line, enter one of the following commands to run the installer and start the upgrade process:

   * **Linux**

     `./pentaho-update-<version>.bin -i silent -DEULA=true -DUSER_INSTALL_DIR=<dir> -DHASH_FILE_ZIP=installer-hash-files-<version>.zip`
   * **Windows**

     `pentaho-update-<version>.exe -i silent -DEULA=true -DUSER_INSTALL_DIR=<dir> -DHASH_FILE_ZIP=installer-hash-files-<version>.zip`

   When the server upgrade process is complete, the console displays an [exit code](/install/9.3-install/pentaho-upgrade-cp/using-the-pentaho-upgrade-installer-in-silent-mode-cp/exit-codes-pentaho-upgrade-installer-silent-mode.md).
3. If any errors occur, review the log file generated by the installer.

   The default location of the log file is `<*root installation directory*>/*Pentaho\_\_Installation*/logs`.
4. If you are upgrading your Pentaho Server, [restart the server](/install/9.3-install/pentaho-configuration/tasks-to-be-performed-by-an-it-administrator/configure-the-pentaho-server/start-and-stop-the-pentaho-server-for-configuration.md).

After upgrading your Pentaho products to version 9.3, complete the [Post-upgrade tasks](/install/9.3-install/pentaho-upgrade-cp/post-upgrade-tasks-pentaho-ugrade-cp.md) to verify that your Pentaho configuration is ready to use.
