# Use silent mode to upgrade archive installation

To upgrade an archive installation without using a graphical interface, use the Pentaho Upgrade Installer in silent mode from a command line.

Perform the following steps to upgrade an archive installation 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 on stopping the server, see [Stop and start the Pentaho Server and repository](/install/10.2-install/pentaho-configuration/tasks-to-be-performed-by-an-it-administrator/configure-the-pentaho-server/stop-and-start-the-pentaho-server-and-repository.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/10.2-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.

   For instructions on starting the server, see [Stop and start the Pentaho Server and repository](/install/10.2-install/pentaho-configuration/tasks-to-be-performed-by-an-it-administrator/configure-the-pentaho-server/stop-and-start-the-pentaho-server-and-repository.md).

After upgrading your Pentaho products to version 10.2, complete the [Post-upgrade tasks](/install/10.2-install/pentaho-upgrade-cp/post-upgrade-tasks-pentaho-ugrade-cp.md) to verify that your Pentaho configuration is ready to use.
