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 22.3 or 22.6 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 9

  2. Create new container environment— Step 10 to Step 114

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 9

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 115 to Step 151 (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 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.

  • NSP auxiliary database

  • NSP analytics servers

10 

If the NSP system includes the WS-NOC, perform the appropriate procedures 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 10 to Step 114

  2. Install and start NSP— Step 115 to Step 151 (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 22.6 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.

  • NSP auxiliary database

  • NSP analytics servers

16 

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