The NTP related configuration will not be migrated. Hence, you need to manually configure the NTP settings in the ZENworks 11 SP4 Appliance again. You must logged into appliance console as root to configure the NTP settings.
If NTP settings are not configured, a time sync warning message is displayed during ZENworks Console (ZCC) login.
Run ZDC to verify the migrated ZENworks 11 SP4 Appliance System.
Ensure that all ZENworks services are running: novell-zenworks-configure -c SystemStatus
