Upgrading BMC Helix Platform Common Services version from 22.4 to 23.2.02

BMC Helix Platform Common Services is a microservices-based platform that provides foundational services (such as user management, tenant management, and single sign-on) and the data lake (such as Elasticsearch, PostgreSQL, and MinIO). BMC Helix Platform Common Services 23.2.02 installation is a pre-requisite for BMC Helix Service Management upgrade. 

Upgrade BMC Helix Platform Common services from version 22.4 to 23.2.02 before you upgrade BMC Helix Service Management.

Important

  • Before you upgrade BMC Helix Platform Common Services, make sure that you perform the following tasks as specified in Upgrading BMC Helix Service Management to 22.1.06.
    • Upgrade Kubernetes and Ingress
    • Delete the Helm revision secrets of the Kubernetes CronJob
  • If you want to use Kubernetes version 1.26, apply the hotfix itom-predeploy-hotfix-23.2.02.002-10 before you upgrade BMC Helix Platform Common Services to version 23.2.02.

Before you begin

  • Make sure that you upgrade Helm to version 3.11
  • Create a new working directory.
    For example, 23.2.02. 
  • Download the deployment manager helix-on-prem-deployment-manager-23.2.02.sh file in the new working directory.
  • Download the itom-predeploy-hotfix-23.2.02.002-10.tar.gz file.
    This file contains the latest deployment size templates.

    To download the deployment manager and itom-predeploy-hotfix-23.2.02.002-10.tar.gz file from EPD, see Downloading the installation files.
  • Download the Cleanup_Bmchelixlogging.sh script.
  • Back up all the PersistentVolumeClaim (PVC) data. 

    Important

    BMC does not have a recommendation for this step. You can use your preferred method to back up the PVC data.

Task 1: To run the upgrade configuration utility

The upgrade configuration utility updates the infra.config and deployment.config files by performing the following tasks:

  • It uses the values that you had set during the deployment of BMC Platform Common Services to configure the infra.config and deployment.config files. 
    You need not manually configure any parameter that you had configured previously.
  • It lists the configuration parameters whose names have been modified in the current release and updates their values automatically.
  • It lists the configuration parameters that were added in the current release.

Perform the following steps to run the upgrade configuration utility:

  1. Go to helix-on-prem-deployment-manager/utilities/upgrade.

  2. Run the following command to provide execution permission to upgrade-configuration.sh

    $chmod a+x ../helix-on-prem-deployment-manager/utilities/upgrade/upgrade-configuration.sh


  3. Run the upgrade configuration utility by using the following command:

    ./upgrade-configuration.sh <namespace>

    <namespace> is the name of the namespace that you used to deploy BMC Helix Platform Common Services .

    The utility updates the infra.config and deployment.config parameters, updates the modified parameters, and if there are any new additions, it prompts you to enter values.
    After the utility has completed updating the infra.config and deployment.config files, you will get a confirmation message. 

    Important

    The infra.config and deployment.config files are configured based on the values that you had set during the previous installation of BMC Helix Platform Common Services. Make sure that you review the files before upgrading.

Task 2: To uninstall BMC Helix Logging

In BMC Helix Platform Common Services 23.2.02, BMC Helix Logging (Elasticsearch, Fluent Bit, and Kibana) is deployed in the BMC Helix Platform namespace, and not in a separate namespace. You must clean up the old EFK and deploy the new EFK during the upgrade.

  1. Back up logs from Kibana into an a Microsoft Excel file.
    1. On the Kibana home page, click .
    2. In the Analytics area, click Discover.
    3. Use a filter to refine your search, click Refresh query.
    4. Save your search.
    5. Select Share > CSV Reports.

    6. Click Generate CSV.
      The system displays a similar message:

    7. When prompted, click Download report and save the report.

  2. Uninstall BMC Helix Logging.
    1. Log in to the system from where you installed BMC Helix Platform Common Services earlier.
    2. Export helm and Kubectl binary path.
      For example:

      export HELM_BIN=/usr/local/bin/helm
      export KUBECTL_BIN=/usr/bin/kubectl
    3. Copy the Cleanup_Bmchelixlogging.sh file to the system.
    4. Clean up the bmc-helix-logging namespace by using the following command: 

      ./Cleanup_Bmchelixlogging.sh <bmc-helix-logging namespace>

      <bmc-helix-logging namespace> is the name of the bmc-helix-logging namespace that you used in the 22.4 version.

Task 3: To apply the hotfix

The hotfix itom-predeploy-hotfix-23.2.02.002-10.tar.gz provides support for Kubernetes version 1.26 and updated deployment size templates. Apply the hotfix by performing the following steps:

  1. Back up the following files:
    • helix-on-prem-deployment-manager directory/deployment-manager.sh
    • commons/preinstall-checker.sh
    • helix-on-prem-deployment-manager directory/configs/infra.config
    • configs/helix-chart-version.config
  2. In the helix-on-prem-deployment-manager directory, copy the itom-predeploy-hotfix-23.2.02.002-10.tar.gz file.
  3. Extract the itom-predeploy-hotfix-23.2.02.002-10.tar.gz file by using the following command:

    tar -xvf itom-predeploy-hotfix-23.2.02.002-10.tar.gz

    After you unzip the file, the following folders are replaced with the new deployment size templates in the helix-on-prem-deployment-manager directory.

    • deployment-manager.sh

    • commons/preinstall-checker.sh

    • configs/infra.config

    • configs/helix-chart-version.config

    • configs/itsmsmall.config 

    • configs/itsmcompact.config 

    • configs/itsmcompact.json 

    • configs/itsmcompact_jvm.config 

    • configs/itsmsmall.json 

    • configs/itsmsmall_jvm.config 

Task 4: To upgrade BMC Helix Platform Common Services

  1. Navigate to your working directory.
  2. In the configs/deployment.config file, make sure that the parameters have following values:

    ParameterValue
    DEPLOYMENT_SIZE

    itsmcompact or itsmsmall

    If you are installing BMC Helix Platform Common Services in a nonproduction environment, specify the value as itsmcompact.

    If you are installing BMC Helix Platform Common Services in a production environment, specify the value as itsmsmall.

    INSTALL_MODEupgrade
    _INFRAyes
    _PTPOSTGRESyes
    _KAFKAyes
    _REDISyes
    _RSSOyes
    _VICTORIAMETRICS

    yes

    Important: For the latest deployment size templates, set this parameter to No if you using only BMC Helix Dashboards and not using BMC Helix ITSM Insights.

    If you have already installed Victoriametrics and not using BMC Helix ITSM Insights, scale down the following pods to zero replicas:

    • victoria-metrics-cluster-vmstorage statefulset
    • victoria-metrics-cluster-vminsert deployment
    • victoria-metrics-cluster-vmselect deployment
    _ELASTICSEARCHyes
    _MINIO yes
  3. For the product services to which you are licensed to, set the value to yes. For all other services, set the value to no.
    To find the product services to which you are licensed to, see the deployment.config file from the version 22.4.
  4. From the working directory, run the deployment manager to upgrade BMC Helix Platform Common Services by using the following command:

    ./deployment-manager.sh

    After the upgrade is complete, you will get the following message:
    Completed Helix On-prem Installation.

  5. (Optional) To view the logs during the upgrade, run the following command:

    tail -f logs/deployment.log
