Update ER2

This section covers the following topics:

Certain data sets, storage formats and components for the Master Server have been updated in Enterprise Recon 2.4. Therefore once the Master Server is updated from ER 2.3.1 (and below) to ER 2.4, the datastore is not backward compatible and downgrading ER 2.4 to an earlier version is not supported.
Please contact the Ground Labs Support Team for assistance with upgrading the Master Server.

Overview

With each new release of ER2, you are recommended to:

  1. Create a backup of the Master Server.
  2. Update the Master Server to access new features and benefit from improvements made to the software.
  3. (Optional) Perform an Agent Upgrade if a feature available in an updated version of the Agent is required.

See the Release Notes for a list of available features for the current version of ER2.

Requirements

To upgrade ER2, the Master Server needs to have:

  • Internet access.
  • Access to the Ground Labs update server at: https://updates.groundlabs.com:8843

Update the Master Server

  1. Create a backup of the Master Server datastore.

  2. In the Master Server console, run as root:

    yum update
    The yum command checks for and displays all available updates for ER2 and the underlying operating system.

    To install only the ER2 update package, run as root:

    yum update er2-master

  3. Enter y to install available updates.

Offline Update

You must download the latest RPM package to update ER2 offline.

  1. Go to Ground Labs Services Portal and log in.
  2. In the Home tab, scroll down to the Download Products section.
  3. Find the latest version of the ER2 RPM package and click Download.
    Download ER2 RPM package in Ground Labs Services Portal.
  4. Transfer the downloaded ER2 RPM package over to a destination directory in the Master Server.
  5. Create a backup of the Master Server.

  6. In the Master Server Console, stop ER2:

    /etc/init.d/er2-master stop

  7. Remove the old er2-master RPM package:

    rpm -e er2-master

  8. Install the updated ER2 RPM package:

    # Where '<directory>' is the full path of where the RPM package resides, and '<RPM file>' is the RPM package to install. # Syntax: rpm -ivh <directory>/<RPM file> rpm -ivh /tmp/er2_rpm_2.x.x_x64.rpm

  9. Restart ER2:

    /etc/init.d/er2-master start

Downgrade ER2

Version downgrades are not supported for the Enterprise Recon Master Server as certain features, data sets, storage formats and / or components in newer versions of Enterprise Recon may not be backward compatible. Downgrading a newer version of the Master Server datastore to an earlier version of Enterprise Recon may leave the system in an undesired state.

Migrating ER2 to CentOS 7

From Enterprise Recon 2.0.28, new installations of Enterprise Recon utilize CentOS 7, which features an updated kernel, improved security features and support for operating system patches and updates until June 2024.

If your existing Master Server installation is based on CentOS 6, Ground Labs strongly recommends that you upgrade to CentOS 7 promptly as CentOS 6 will reach end of life on November 30, 2020. The Ground Labs Support Team is available to assist customers who wish to migrate their existing installations to CentOS 7.

Ground Labs will continue to support existing Enterprise Recon installations based on CentOS 6 until its end of life date on November 30, 2020.
