CAUTION

Service Disruption

A redundant NFM-P system upgrade involves a network management outage.

Ensure that you perform the upgrade during a scheduled maintenance period of sufficient duration to accommodate the outage.

During a redundant NFM-P system upgrade, the primary and standby roles of the main servers and databases reverse, as do the Preferred and Reserved auxiliary server roles. As a result, the use of relative component identifiers such as primary and standby can cause confusion.

To clearly identify components during a redundant system upgrade, you can use the figure below. The components on the left manage the network before the upgrade, and the components on the right manage the network after the upgrade. Each component in the figure has an absolute identifier in brackets, for example, [DB1], that clearly identifies the component in the redundant system upgrade workflow and procedure steps.
