Upgrading

This section describes the upgrade and migration options that are available from previous versions of BMC Discovery. BMC Discovery 24.1 is supported on Oracle Linux 9.

Back up before upgrading

The upgrade to BMC Discovery 24.1 is fully tested and supported, and from previous releases running on Red Hat Enterprise Linux 7 or CentOS 7 is more significant than previous upgrades. The upgrade is complex, and involves a change of two major versions: from Red Hat Enterprise Linux 7 or CentOS 7 to Oracle Linux 9. During the upgrade, the BMC Discovery product is uninstalled and then reinstalled, if for any reason, the upgrade fails at that time, the BMC Discovery product cannot resolve any upgrade issues.

Before you upgrade, you should back up the appliance, or for clusters, each cluster member. Use the SSH or Windows Share backup method.

If you are using a virtual appliance, you should shutdown and take a snapshot of the virtual machine. For a cluster of virtual appliances, you should shutdown all the virtual machines at the same time and snapshot them at the same time. For example, if you are using VMware, use the vSphere Client to shutdown the virtual machines and take the snapshot.
