Upgrading Synthetic Data Generator from Version 4.8 to Version 5.0

An instance administrator can upgrade Synthetic Data Generator from Cloud Pak for Data Version 4.8 to Version 5.0.

Who needs to complete this task?

Instance administrator To upgrade Synthetic Data Generator, you must be an instance administrator. An instance administrator has permission to manage software in the following projects:

The operators project for the instance

The operators for this instance of Synthetic Data Generator are installed in the operators project. In the upgrade commands, the ${PROJECT_CPD_INST_OPERATORS} environment variable refers to the operators project.

The operands project for the instance

The custom resources for the control plane and Synthetic Data Generator are installed in the operands project. In the upgrade commands, the ${PROJECT_CPD_INST_OPERANDS} environment variable refers to the operands project.

When do you need to complete this task?

Review the following options to determine whether you need to complete this task:

  • If you want to upgrade the Cloud Pak for Data control plane and one or more services at the same time, follow the process in Upgrading an instance of Cloud Pak for Data instead.
  • If you didn't upgrade Synthetic Data Generator when you upgraded the Cloud Pak for Data control plane, complete this task to upgrade Synthetic Data Generator.

    Repeat as needed If you are responsible for multiple instances of Cloud Pak for Data, you can repeat this task to upgrade more instances of Synthetic Data Generator on the cluster.

Information you need to complete this task

Review the following information before you upgrade Synthetic Data Generator:

Version requirements

All the components that are associated with an instance of Cloud Pak for Data must be installed at the same release. For example, if the Cloud Pak for Data control plane is at Version 5.0.3, you must upgrade Synthetic Data Generator to Version 5.0.3.

Environment variables
The commands in this task use environment variables so that you can run the commands exactly as written.
  • If you do not have the script that defines the environment variables, see Setting up installation environment variables.
  • To use the environment variables from the script, you must source the environment variables before you run the commands in this task. For example, run:
    source ./cpd_vars.sh
Common core services
Synthetic Data Generator requires the Cloud Pak for Data common core services.

If the common core services are not at the correct version in the operands project for the instance, the common core services are automatically upgraded when you upgrade Synthetic Data Generator. The common core services upgrade increases the amount of time the upgrade takes to complete.

Storage requirements
Specify the storage that you use in your existing installation. You cannot change the storage that is associated with Synthetic Data Generator during an upgrade. Ensure that the environment variables point to the correct storage classes for your environment.

Before you begin

This task assumes that the following prerequisites are met:

Prerequisite Where to find more information
The cluster meets the minimum requirements for Synthetic Data Generator. If this task is not complete, see System requirements.
The workstation from which you will run the upgrade is set up as a client workstation and has the following command-line interfaces:
  • Cloud Pak for Data CLI: cpd-cli
  • OpenShift® CLI: oc
 If this task is not complete, see Updating client workstations.
The Cloud Pak for Data control plane is upgraded. If this task is not complete, see Upgrading an instance of Cloud Pak for Data.
For environments that use a private container registry, such as air-gapped environments, the Synthetic Data Generator software images are mirrored to the private container registry. If this task is not complete, see Mirroring images to a private container registry.
For environments that use a private container registry, such as air-gapped environments, the cpd-cli is configured to pull the olm-utils-v3 image from the private container registry. If this task is not complete, see Pulling the olm-utils-v3 image from the private container registry.

Procedure

Complete the following tasks to upgrade Synthetic Data Generator:

  1. Upgrading the service
  2. Validating the upgrade
  3. What to do next

Upgrading the service

Important: The Operator Lifecycle Manager (OLM) objects for Synthetic Data Generator were updated when you upgraded the Cloud Pak for Data platform. The cpd-cli manage apply-olm updates all of the OLM objects in the operators project at the same time.

To upgrade Synthetic Data Generator:

  1. Log the cpd-cli in to the Red Hat® OpenShift Container Platform cluster:
    ${CPDM_OC_LOGIN}
    Remember: CPDM_OC_LOGIN is an alias for the cpd-cli manage login-to-ocp command.
  2. Update the custom resource for Synthetic Data Generator.

    The command that you run depends on the storage on your cluster:

    Red Hat OpenShift Data Foundation storage

    Run the following command to create the custom resource.

    cpd-cli manage apply-cr \
--components=syntheticdata \
--release=${VERSION} \
--cpd_instance_ns=${PROJECT_CPD_INST_OPERANDS} \
--block_storage_class=${STG_CLASS_BLOCK} \

--license_acceptance=true \
--upgrade=true
    IBM Storage Fusion Data Foundation storage

    Run the following command to create the custom resource.

Validating the upgrade

Synthetic Data Generator is upgraded when the apply-cr command returns:
[SUCCESS]... The apply-cr command ran successfully

If you want to confirm that the custom resource status is Completed, you can run the cpd-cli manage get-cr-status command:

cpd-cli manage get-cr-status \
--cpd_instance_ns=${PROJECT_CPD_INST_OPERANDS} \
--components=syntheticdata
