Uninstalling the upgrade

Before you begin

  • Make sure you downgrade the Sensors before you downgrade the Manager. Similarly, you must downgrade the Managers before you downgrade a Central Manager.
    Note: To downgrade Sensor software, see the relevant McAfee KnowledgeBase articles.
  • Make sure you have the database backup from the Manager version that you want to downgrade to. For example, if you want to downgrade from 9.2 to 9.1, then you must have the database backup from 9.1 Manager.

If for some reason the upgrade is not suitable, you can uninstall the 9.2 version and reinstall the previous version.

Task

  1. Stop the Manager service by following one of these steps:
    • Right-click on the Manager icon at the bottom-right corner of your server and stop the service.
    • Select Windows Control PanelAdministrative ToolsServices. Then right-click on McAfee Network Security Manager and select Stop.
  2. Stop the McAfee Network Security Manager Watchdog service using the same method as described in step 1.
  3. Uninstall the 9.2 software that you upgraded to.
  4. Delete the Network Security Platform install directory (including the MariaDB install directory).
  5. Reinstall the earlier version from which you upgraded.
  6. Restore the corresponding database backup.
    For example, if you had downgraded from 9.2 to 9.1, then restore your 9.1 database backup.
    Note: Downgrade all Managers prior to the Central Manager downgrade.
