This section describes the installation, migration, and upgrade options that are available from previous versions of BMC Atrium Discovery.

Why a migration and major version change?

The changes introduced moving from BMC Atrium Discovery version 8.3.x to 9.0 are very significant.

  • Red Hat Enterprise Linux 6 – the operating system has been changed from Red Hat Enterprise Linux (RHEL) version 5 to version 6. Red Hat does not support in-place upgrades between any major versions of Red Hat Enterprise Linux. Consequently, there is no direct upgrade path between BMC Atrium Discovery version 8.3.x and version BMC Atrium Discovery 9.0 running on RHEL 6.
  • Support for IPv6 – many of the core areas of the product have been affected by the introduction of IPv6 support.
  • Networking model changes – the model has changed most significantly in the networking area, partly in support of IPv6, but also to cater for complex network configurations, and SNMP managed devices. The model has also been made more consistent, in particular the harmonization of some attributes across the root nodes.
  • New datastore – the datastore has been substantially refactored to prepare for larger scale deployments which may be supported in future releases. In addition it now supports phrase searches.

The move to Red Hat 6 alone prevents a straightforward upgrade and necessitate a change of major version number. The model changes and introduction of IPv6 support would also require a change of major version number.

Installation, migration, and upgrade options

At some stage, when moving from BMC Atrium Discovery version 8.3.x to version 9.0, you will need to migrate, or backup a version 9.0 appliance on RHEL 5 and restore it onto a version 9.0 appliance on RHEL 6, which is essentially the same as migration. This is summarized in the following diagram.

Installation

New installations of BMC Atrium Discovery version 9.0 are installed from a kickstart DVD or a downloaded Open Virtualization Format (OVF) virtual machine. See Installing BMC Atrium Discovery and Installing the virtual appliance for more information.

Upgrade – 8.3.x to 9.0 on RHEL 5

An upgrade is possible to BMC Atrium Discovery version 9.0 running on RHEL 5. This enables you to use many of the new features introduced in BMC Atrium Discovery 9.0, but does not fully support IPv6. This is described in Upgrading to version 9.0.

Migration – 8.3.x to 9.0 on RHEL 6

There is no direct upgrade path between BMC Atrium Discovery version 8.3.x and version BMC Atrium Discovery 9.0 running on RHEL 6. Rather, a migration is required. The migration procedure is described in Migrating from version 8.3.x to 9.0.

Migration – 7.5 to 9.0 on RHEL 6

There is no direct upgrade path between BMC Atrium Discovery version 7.5 (BMC Topology Discovery and Foundation Discovery) and any later version of BMC Atrium Discovery. In this case too, a migration is required. This migration procedure is described in Migrating from version 7.5 to 9.0.
