Upgrading using a USB key

Last Updated : Mar 03, 2026 |
You can upgrade a server using a bootable USB key. This can be an automatic upgrade.
Note:

On Avaya Solutions Platform (ASP) 110 servers, specifically Dell R640 or R660, upgrading IP Office Release to 12.3 from any previous 12.x version using the USB method is not recommended. Instead, all upgrades to 12.3 releases must be performed through Web Manager using the IP Office file transfer (ISO) method.

Before you begin

  • You must obtain and check all relevant release notes and documentation prior to any upgrade.

  • Ensure that you have backed up the server before performing the upgrade. See Backup and Restore.

  • Some upgrades require a new set of licenses, typically when upgrading to another major release rather than to a service pack or feature pack within the current release. Obtain and install the new license file before upgrading. A license file for a higher release will still allow the existing release to continue operating.

  • If the server is part of a network of IP Office servers:

    • The primary server must be upgraded first.

    • Once the primary server has been upgraded, any other servers can be upgraded individually or simultaneously.

  • Upgrading will cause service disruption and end calls in progress. If possible it should be performed outside normal business hours. Using ISO transfer and upgrade through web manager is recommended as that method allows for scheduled upgrading if required.

  • Download the ISO file for the release from the Avaya support site (https://support.avaya.com).

  • Also download any related documentation from the same page as the ISO file.

Procedure

  1. Insert the installation USB drive in the USB port of the server.
  2. Start the server.
  3. On a Dell R260 or R660 based server, access the One Time Boot Menu by pressing F12 when you see the Dell logo. In the menu:
    1. Use the cursor keys to select the USB memory key.
    2. Press Enter to start a boot from the USB memory key.
  4. The upgrade proceeds automatically. When completed, remove the USB key and allow the server to restart again.
