Installation, migration, and upgrade overview

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

Upgrade

You can only upgrade to BMC Atrium Discovery version 10.0 from 9.0.x prior to but not including SP3 on Red Hat Enterprise Linux 6. This is described in Upgrading to version 10.0.

New SSL certificates in BMC Atrium Discovery 10.0

BMC Atrium Discovery 10.0 is shipped with new SSL certificates

The default SSL certificates used in earlier versions of BMC Atrium Discovery expire in 2015. BMC Atrium Discovery version 10.0 ships with new SSL certificates. When upgrading from 9.x to 10.0 the default SSL certificates are updated automatically on the BMC Atrium Discovery appliance and Windows proxies. However, BMC Atrium Discovery 8.3 Windows proxies will no longer work with a BMC Atrium Discovery version 10.0 appliance, and need their CA certificates manually updated to do so. It is highly recommended that you re-install these Windows proxies before using them with BMC Atrium Discovery 10.0. If you have installed your own keys, these are not modified or overwritten in any way by the upgrade or migration process.

No architecture changes required

When upgrading from 9.x to 10.0 there is no need to change your deployment architecture. Rather, BMC strongly recommend that you upgrade using your existing architecture and test version 10.0 in a known configuration. If testing reveals that you require the performance improvements offered by a cluster, you can then add hardware and replace one or more version 10 machines with a cluster.

Migration

To move from any BMC Atrium Discovery version before 9.0 you must 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. You must migrate to RHEL 6 on a version 9.0.x appliance. This is summarized in the following diagram.

Installation

New installations of BMC Atrium Discovery version 10.0 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.

Upgrading from BMC Atrium Discovery version 10

BMC Atrium Discovery version 10 introduces a UI based upgrade which enables you to upgrade standalone machines and clusters from a single UI.
