Workflow for DR NSP system upgrade from Release 22.6 or earlier

Purpose

The following is the sequence of high-level actions involved in the upgrade of a DR Release 22.6 or earlier NSP system.

Stages
Prepare for upgrade
 
1 

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

Upgrade standby NSP cluster
 
2 

In the standby data center, perform To prepare for an NSP system upgrade from Release 22.6 or earlier, to 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

3 

In the standby data center, perform the following phases of To upgrade a Release 22.6 or earlier NSP cluster; each phase has links to step sections in the procedure.

  1. Disable existing cluster— Step 1 to Step 8

  2. Create new container environment— Step 9 to Step 112

Note: The standby cluster, which becomes the new primary cluster, is not started until after you stop the primary cluster.

Prepare primary NSP cluster for upgrade
 
4 

In the primary data center, perform To prepare for an NSP system upgrade from Release 22.6 or earlier to do the following:

  • back up the NSP software configuration, databases, and system data

  • download the NSP installation software

  • verify the cluster readiness for the upgrade

  • perform special upgrade preconfiguration

5 

In the primary data center, perform the following phase of To upgrade a Release 22.6 or earlier NSP cluster .

Disable existing cluster— Step 1 to Step 8

Configure and start new primary (former standby) NSP cluster
 
6 

In the standby data center, perform the following phase of To upgrade a Release 22.6 or earlier NSP cluster.

Configure and start NSP cluster— Step 113 to Step 135 (end of procedure)

Perform sanity check of new primary NSP cluster
 
7 

On the new primary NSP cluster, 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 primary components and systems
 
8 

If the NSP deployment includes the VSR-NRC, upgrade the VSR-NRC In the new primary (former standby) data center, as described in the VSR-NRC documentation.

9 

If you are including an existing NFM-P system at an earlier release in the deployment, perform one of the following In the new primary (former standby) data center.

  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

10 

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.

Upgrade new standby (former primary) NSP cluster
 
11 

In the former primary data center, perform the following phases of To upgrade a Release 22.6 or earlier NSP cluster.

  1. Create new container environment— Step 9 to Step 112

  2. Install and start NSP— Step 113 to Step 135 (end of procedure)

Perform sanity check of new standby NSP cluster
 
12 

Use a browser to open the standby NSP cluster URL.

13 

Verify the following.

  • The browser is redirected to the primary cluster address.

  • The NSP sign-in page opens.

  • The NSP UI opens after you sign in.

Upgrade or enable additional standby components and systems
 
14 

If the NSP deployment includes the VSR-NRC, upgrade the VSR-NRC In the new standby (former primary) data center, as described in the VSR-NRC documentation.

15 

If you are including an existing NFM-P system at an earlier release in the deployment, perform one of the following In the new standby (former primary) data center.

  1. Upgrade the NFM-P to the NSP release; see NFM-P system upgrade from Release 22.9 or later.

  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

16 

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.
