Upgrading Netezza Performance Server

Deployment options: Netezza Performance Server for Cloud Pak for Data

After you determined your upgrade path, upgrade Netezza Performance Server.

Before you begin

If you use NFS storage for Cloud Pak for Data, you must update the storage before you upgrade Cloud Pak for Data. For more information, see Setting up NFS storage.

Procedure

To upgrade Red Hat OpenShift, Netezza Performance Server, the nz-cloud components, and Cloud Pak for Data, run the nz-cloud command with the -all option specified
```
./nz-cloud -u all --to [VERSION1,VERSION2,VERSION3,TARGET_VERSION] -p aws_infra.properties -v
```
[VERSION1,VERSION2,VERSION3,TARGET_VERSION]] specify the intermediate Red Hat OpenShift versions. Separate every intermediate version with a comma.

You do not have to include the current version that you are on.
Example:
```
./nz-cloud -u all --to [4.6.54,4.7.47,4.8.51,4.9.50,4.10.37] -p aws_infra.properties -v
```
Note:
1. This upgrade type requires a maintenance window for the Cloud Pak for Data and Netezza Performance Server instances. When you upgrade Red Hat OpenShift, the Netezza Performance Server instance is paused automatically. Also, the Cloud Pak for Data web console is in the maintenance mode and unavailable during the upgrade. The instance is brought online after the upgrade.
2. The Red Hat OpenShift upgrade time depends on the number of intermediate versions in the list. Approximately, it takes 1 - 2 hours. It takes around 3 hours to upgrade the rest of the components.
  Run the following command to monitor the Red Hat OpenShift upgrade:
  watch 'oc get clusterversion; echo; oc get co'
3. If Red Hat OpenShift upgrade fails and oc adm upgrade reports Upgradeable=False, wait until the command no longer shows this state before you try to upgrade again.
To upgrade only Red Hat OpenShift, run the nz-cloud command with the -ocp option specified.
```
./nz-cloud -u ocp --to [VERSION1,VERSION2,VERSION3,TARGET_VERSION] -p aws_infra.properties -v
```
If any Red Hat OpenShift operator goes into the Degraded state during the upgrade, for example openshift-samples, search failure message on the Red Hat OpenShift solutions page and follow the suggested steps.
To upgrade a specific component, run the nz-cloud command with the component name specified.
```
./nz-cloud -u COMPONENT_NAME -p aws_infra.properties -v
```
Tip: It is suggested that you use the -u all option, which automatically handles the whole upgrade procedure.
Example:
- Upgrading only Cloud Pak for Data:
```
./nz-cloud -u cpd -p aws_infra.properties -v
```
- Upgrading only the nz-cloud components:
```
./nz-cloud -u nps-addon -p aws_infra.properties -v
```
- Upgrading only the Netezza Performance Server instance:
```
./nz-cloud -u nps-instance -p aws_infra.properties -v
```
