Prepare for upgrade

Perform To prepare for an NSP system upgrade from Release 22.6 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

Upgrade NSP cluster

Perform the following phases of To upgrade a Release 22.6 or earlier NSP cluster. Each phase consists of a series of high-level action links that lead to step sections in the procedure.

1. Disable existing cluster— Step 1 to Step 8

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

   • Uninstall IPRC, CDRC

   • Preserve NSP cluster configuration

2. Create new container environment— Step 9 to Step 83

   • Create NSP deployer host

   • Configure NSP deployer host network interface

   • Install NSP Kubernetes registry

   • Migrate legacy cluster parameters

   • Create NSP cluster VMs

   • Configure NSP cluster interfaces

   • Deploy container environment

3. Install and deploy NSP software— Step 84 to Step 135 (end of procedure)

   • Restore NSP system configuration

   • Label NSP cluster nodes

   • Configure NSP software

   • Restore dedicated MDM node labels

   • Deploy NSP cluster

   • Restore NSP data

   • Start NSP

   • Monitor NSP initialization—successful startup marks the end of the network visibility loss

   • Verify upgraded NSP cluster operation

   • Upgrade MDM adaptors

   • Synchronize auxiliary database password

   • Perform post-upgrade tasks

Perform sanity check of upgraded system

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's service management views

Upgrade or enable additional components and systems

If the NSP deployment includes the VSR-NRC, upgrade the VSR-NRC as described in the VSR-NRC documentation.

If you are including an existing NFM-P system at an earlier release in the deployment, perform one of the following.

1. Upgrade the NFM-P to the NSP release; see NFM-P system upgrade from Release 22.6 or earlier.

2. Enable NFM-P and NSP compatibility; perform To enable NSP compatibility with an earlier NFM-P system.

Note: An NFM-P system upgrade procedure includes steps for upgrading the following components in an orderly fashion.

• auxiliary database

• NSP Flow Collectors / Flow Collector Controllers

• NSP analytics servers

If the NSP system includes the WS-NOC, perform the appropriate procedure in WS-NOC and NSP integration to enable WS-NOC integration with the upgraded NSP system.
