Upgrading BMC Helix IT Operations Management from version 23.2.02 to 23.4.00

Before you begin

Make sure that you have performed all the steps listed in the Preparing for upgrade topic.

To upgrade BMC Helix IT Operations Management

1. In the new_working_directory/ configs/deployment.config file, make sure that your deployment size is the same as your previous deployment size, for example, small, compact, medium, or large.
   To confirm your deployment size, see the value set for the DEPLOYMENT_SIZE parameter in the configs/ deployment.config file in BMC Helix IT Operations Management version 23.2.02.
2. In the new_working_directory/ configs/deployment.config file, update the following values:
   1. Set the value of INSTALL_MODE to upgrade.
   2. Set the values of the following services to yes.

      • _KAFKA
      • _REDIS
      • _RSSO
      • _VICTORIAMETRICS
      • _ELASTICSEARCH
      • _MINIO
   3. For all the BMC Helix IT Operations Managementservices for which you are licensed, set the value to yes; for all other services, set the value to no.
      For example, if you are only licensed to use BMC Helix Operations Management and BMC Helix Continuous Optimization:

      • To use BMC Helix Operations Management, set value of MONITOR to yes.

        (Optionally)

        • If you want to use AIOps, set AIOPS_SERVICES to yes.
        • If you want to use Log Analytics, set INTELLI_INT_SERVICES to yes.

      • To use BMC Helix Continuous Optimization, set the value of OPTIMIZE to yes.
