Workflow for DR NSP system upgrade from Release 22.9 or later

Purpose

Table 9-1, DR system upgrade actions, by NSP cluster lists the sequence of high-level actions involved in the upgrade of a DR Release 22.9 or later NSP system. The table has a separate column for each NSP cluster.

Concurrent task execution

You can perform some upgrade actions on each cluster at the same time. Actions that you can perform concurrently on each cluster are in table rows that span the Primary NSP cluster and Standby NSP cluster columns.

Perform “How do I display the NSP cluster status?” in the NSP System Administrator Guide to:

  • identify the primary and standby NSP clusters

  • verify the operational state of each NSP cluster

Perform To prepare for an NSP system upgrade from Release 22.9 or laterto do the following:

  • back up the NSP software configuration

  • download the NSP installation software

  • verify the cluster readiness for the upgrade

  • perform special upgrade preconfiguration

The remaining links in the table lead to step sections in To upgrade a Release 22.9 or later NSP cluster.
