Upgrading the managed unit

Upgrade your managed units after upgrading your central manager.

Applying health check patch
The health check patch performs preliminary checks on your Guardium® system to prevent potential issues during the upgrade. This patch must be successfully installed in the last seven days before you install the Guardium upgrade patch. Use the following procedure to distribute the health check patch to your managed units by using the Central Management page on the central manager.
Archiving data
You can archive the audit data that is captured by your Guardium system to another location. These archived files can be restored later for forensic purposes without replacing the audit data that is already available in your Guardium system. Use the following procedure to archive the data on your managed unit.
Purging system data
Purging unnecessary data from your managed unit can significantly speed up the upgrade process. For best performance and to minimize risks that are associated with upgrading large amounts of data, try to achieve less than 20% internal database utilization by purging unnecessary system data.
Backing up the system
System backups store all the necessary data and configuration values to restore your Guardium system. Use the following procedure to back up a managed unit in your centrally managed environment.
Applying the upgrade patch
Upgrade your managed unit by distributing the upgrade patch from the central manager. Upgrade the aggregators first before you upgrade collectors.
Installing maintenance patches
Distribute the maintenance patches to your managed units by using the Central Management page on the central manager.
