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 10.1 from 10.0.x or 9.x running on RHEL 6. This is described in Upgrading to version 10.1.

No architecture changes required

When upgrading from 9.x to 10.x there is no need to change your deployment architecture. Rather, BMC strongly recommend that you upgrade using your existing architecture and test version 10.x 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.x 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.
