Important Notes
Pre-installation Check List
Before you start the installation of WDM 5.7.1, do the following:
 Prior to the start of the installation, ensure that all scheduled packages are completed.
This is required to ensure that no device-specific updates are pending while a WDM
upgrade is in progress.
 Make sure that all the WDM GUI instances that are running locally or remotely are
closed prior to starting the upgrade.
 Prior to the installation make sure that all local and remote connections to the WDM
server are closed and all WDM GUI sessions are closed when the hotfix installation is
in progress.
Note: You cannot uninstall this version after you install it.
Steps to Install WDM 5.7.1 on a Distributed Environment
If you are having a distributed setup where all the WDM components are installed on
separate systems, then make sure to install on the following components:
 WDM Server
 One or more WDM GUI Consoles
 WDM Web GUI
 One or more Remote Software Repositories
 WDM Master Software Repository
 You do not need to install on the WDM Database as this gets updated when you run
the hotfix on the WDM Server.
