Pathway for standalone NSP system upgrade from Release 25.8 or earlier

Purpose

Use this pathway through the documentation to access detailed procedures for upgrading a standalone NSP system. Table 8-1, Pathway for concurrent task execution during standalone NSP system upgrade from 25.8 or earlier lists the system upgrade pathway tasks.

Concurrent task execution

Some system upgrade operations require considerable time. To reduce the duration of a standalone system upgrade, you can perform some actions concurrently.

Note: The Upgrade standalone system links lead to sections in To upgrade a standalone NFM-P system.

Note: If your NSP deployment includes NFM-P on a release earlier than Release 24.4 and an auxiliary database is installed, you must follow the auxiliary database steps specified in General NFM-P upgrade pathway.

	Operator actions
	Perform To prepare for an NSP system upgrade from Release 25.8 or earlier to do the following: back up the NSP system configuration, databases, and file service data download the NSP installation software verify the cluster readiness for the upgrade perform special upgrade preconfiguration

	Verify various NSP system functions by performing actions such as: comparing the benchmarks recorded before the upgrade to the current indicators verifying NSP UI access verifying the service list in NSP service management views

Operator actions

Perform To prepare for an NSP system upgrade from Release 25.8 or earlier to do the following:

back up the NSP system configuration, databases, and file service data
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 25.8 or earlier NSP cluster.

Disable existing cluster— Step 1 to Step 5

Stop and undeploy NSP cluster—marks the beginning of the network visibility loss associated with the upgrade
Preserve NSP cluster configuration

Create new container environment— Step 6 to Step 52

Install and deploy NSP software— Step 53 to Step 106

Restore NSP system files

The following operations can be performed concurrently

Configure NSP software
Upgrade auxiliary database

Note: Skip this stage if your deployment includes NFM-P.

Restore Kubernetes secrets
Deploy NSP cluster
Restore NSP data
Start NSP
Monitor NSP initialization—successful startup marks the end of the network visibility loss

Verify NSP system upgrade— Step 107 to Step 123 (end of procedure)

Verify various NSP system functions by performing actions such as:

comparing the benchmarks recorded before the upgrade to the current indicators
verifying NSP UI access
verifying the service list in NSP service management views
