Configuring after upgrade

The post-upgrade activities that you might consider are the same as post-installation activities. If you have already performed these configuration steps, they are retained on upgrade and do not need to be repeated.

After you upgrade to 22.1, the UI displays a set of tasks that you must complete. The following sections list all the possible tasks. These tasks can vary in your case, depending on the version and configuration of your system before upgrading.

Transitioning to scopes/overlapping IP addresses 

The BMC Discovery 20.08 release introduced scopes, a means of distinguishing overlapping IP addresses.  On upgrade to BMC Discovery from versions before 20.08, all existing discovered devices are considered to be in the default scope. When you scan an endpoint, all scanned devices appear in the scan's scope and will be distinct from devices scanned in any other scope.

However, if an endpoint has already been discovered, and is then scanned using a non-default scope, this creates a duplicate inferred device. To avoid this, upgraded appliances use scope transition mode, where discovered endpoints that do not exist in the scan's scope are matched against existing endpoints in the default scope. If the endpoint is the same, it is updated, including the addition of the scope.

All AWS EC2 hosts have a scope whether discovered by using AWS Systems Manager or ssh, and scope transition mode will update existing EC2 the updated host scripts with the scope.

When you upgrade to BMC Discovery 23.1 from a version earlier than 20.08, and choose to use scope, you should leave the appliance in transition mode until you have scanned the endpoints covered by the BMC Discovery Outposts or appliances where scope has been configured.

If you do not have overlapping IP addresses and do not scan, or do not plan to scan, AWS EC2 hosts by using Systems Manager (SSM) or Google Compute Engine hosts running in Google Cloud Platform, you do not need to consider scopes.

To remove legacy network devices imported from CiscoWorks

CiscoWorks import was deprecated in BMC Discovery 11.0 and removed in version 20.02 (12.0). If you have any legacy imported CiscoWorks network devices, you should remove them. You can find the legacy imported CiscoWorks network devices using the following generic search query: 

SEARCH NetworkDevice WHERE type = "Imported Switch"

The resulting list page shows the network devices and you can remove them using the UI controls. Select All, and then Actions > Destroy..

To ensure that Integration Points are converted to Data Sources

Data sources are a flexible and intuitive way to add static sources of information to your discovered information. Data sources replace the 'Integration Points' used in previous releases. The upgrade from BMC Discovery 11.3 to 23.1 converts any existing Integration Points to database data sources. The name of converted Integration Points is ip_name.connection_name, where ip_name is the name of the Integration Point, and connection_name is the name of the connection used for the Integration Point. You should ensure that your converted Integration Points are available on the Data Sources page.

Integration Point patterns using definition blocks continue to work.

Consolidation continues to work correctly to BMC Discovery 23.1 consolidating appliances, whether or not the scanning appliance is upgraded.  See Consolidation for more details on BMC Discovery versions and consolidation.

To re-authenticate the AIM provider with the CyberArk vault

If you upgrade from BMC Discovery 11.x and you have configured  a CyberArk integration, you must re-authenticate the AIM provider with the CyberArk vault. For information on re-authenticating the AIM provider, see Integrating with CyberArk Enterprise Password Vault.

To activate the new TKU with the latest patterns

If you upgrade from a 21.3 system that has TKU 2022-01-1-ADDM-12.3+ installed, after upgrade to 22.1, the Knowledge management UI shows that the installed version is TKU 2022-01-1-ADDM-12.4+. In this case you must activate the new TKU before performing discovery. If you do not activate the new TKU, the pre-upgrade patterns remain active.

If you upgrade from a 21.3 system that has TKU 2022-02-1-ADDM-12.3+ installed, after upgrade to 22.1, the Knowledge management UI shows that the installed version is TKU 2022-01-1-ADDM-12.3+. In this case you should upload TKU 2022-02-1-ADDM-12.4+ before performing discovery.

For additional information, see Knowledge management and  latest TKU activation Open link .

From BMC Discovery 20.02 (12.0) and onwards, TKU devices and product content are no longer the same for all versions. When updating TKUs in future, insure that you download and install the correct version.

To reapply customizations to the new Discovery scripts

Where this topic refers to default scripts, it refers to the discovery scripts that were shipped with the release. For example, in a version 21.3 (12.3) appliance, the default scripts are those that shipped with 21.3 (12.3). If you upgrade the appliance to version 22.1, the default scripts become those that shipped with version 22.1.

When you upgrade from one BMC Discovery version to a later version, the discovery scripts may change to implement the new capabilities of the release or to fix defects in the scripts. The new scripts replace the default scripts from the previous release. However, if you have customized any discovery scripts, those are not replaced. Platforms with modified scripts are shown on the Discovery Platforms page with a change bar. When you click through to the platform page you can see the individual scripts that have been modified. Where a script has been modified you are provided with the following additional controls:

  • Show Differences – shows side by side versions of the current file and the modified file with highlighted changes. Use this view to identify your modifications, and the changes made during the upgrade, and decide how to move your changes to the new default script.
  • Reset To Default – replaces the modified file with the new default script.

Important

If you customize the default scripts, they are not upgraded automatically when you upgrade BMC Discovery. You must ensure that you update the scripts manually, incorporating your changes. Alternatively, you can leverage the new version's defaults by using the Reset To Default option.
