For this use case, post-upgrade checks, show commands, and node configs are run on the nodes and compared to pre-upgrade.

NSP post-upgrade checks:

• Node version in Device Management is updated to the new version

• Network Health View, Network Map View, and Inventory View are updated as expected

Additional NSP checks depend on NSP-enabled features. Some possible checks include:

• Service Management - all services are in the same state pre-upgrade

• Configuration Deployments (ICM) - deployment status is the same pre-upgrade

• Telemetry - stats collection works as expected post-upgrade

• OAM tests continue to pass post-node upgrade

The following are examples of commands run during Pre-check. Run the commands again, then save the output to a file and compare it to the pre-upgrade output.
