Dell Update Packages Version 14.11.201 User's Guide

Important Tips to Remember for Using DUPs

  • Prepare repair disks before you perform any updates.
  • Download the currently installed version of drivers, BIOS, and firmware, so that you have a backup plan in case of any issues.
  • Make sure that you have a backup of operating system files or system configuration files stored on a system other than the one you are updating.
  • Make sure that the updates are planned for and performed by the system administrator who knows which applications could be affected.
  • Before updating all systems, perform the upgrade on one nonessential system to test the update.
  • Do not run other applications while executing DUPs.
  • On a Microsoft Hyper-V virtual machine, while updating the host operating system components, ensure that the guest operating systems are not running.
  • Do not shut down the system while an update is in progress.
  • Make sure that the system reboots without power interruption after performing a BIOS update.
  • Do not close any terminal console windows used for performing the DUP CLI execution, while DUP executions are in progress.
