Upgrading BMC Helix Platform services version from 23.1.02 to 23.2.02

BMC Helix Platform services upgrade is a pre-requisite for BMC Helix Service Management upgrade. BMC Helix Service Management uses the following services provided by BMC Helix Platform:

• Infrastructure services
• Common services
• BMC Helix Dashboards
• BMC Helix ITSM Insights

Upgrade BMC Helix Platform services from version 23.1.02 to 23.2.02 before you upgrade BMC Helix Service Management.

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 following files from EPD:
  
  • Download the deployment manager helix-on-prem-deployment-manager-23.2.02.sh file in the new working directory.
    
  • Download the upgrade configuration utility.
    To download the deployment manager and upgrade configuration utility from EPD, see Downloading-the-installation-files. 

• 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.

• Run the upgrade configuration utility.

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 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 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 services. Make sure that you review the files before upgrading.

1. Navigate to your working directory.

2. In the configs/deployment.config file, make sure that the parameters have following values:

   To find the product services to which you are licensed to, see the deployment.config file from the version 23.1.02.

4. From the working directory, run the deployment manager to upgrade BMC Helix Platform services by using the following command:

   ./deployment-manager.sh
