Upgrade DEM Collector with Update Manager

For DEM Collector versions 3.9 and above (formerly RUM Agent), users can upgrade to the latest version by installing the service pack (.ppm file) over the existing DEM Collector installation. The service pack typically includes bug fixes and new feature additions. This document provides instructions on how to use the Update Manager to install the Service Pack over the DEM Collector.

Note:

  • The Update Manager incorporates useful validation features, including compatibility checks. It prevents the installation of an incompatible service pack, ensuring a seamless upgrade process.
  • The Update Manager for the DEM Collector is only supported for DEM Collector version v3.9 and above.

Steps to install Service Pack

Key Instructions: 

  • Start the command line option (Windows) as an administrator [cmd → run as the administrator]. Click here to see the screenshot.
  • <DEM Collector Home> refers to the directory in which you have installed the DEM Collector. This directory location is specified by you when you install the agent. For example, C:/Program Files/ManageEngine/DEMCollector. This script invokes the Update Manager tool.

Download Service Pack

  1. Download the latest service pack from the provided link in the PPM archive file. Place the downloaded file inside a folder on the machine where the DEM Collector is installed.

  2. If prompted, you may need to import the ManageEngine public key certificate file during the upgrade process. Please download the latest certificate file (.crt) from this link and have it ready.

    Note: This is a one-time process done to verify the integrity of the PPM file.
