Key questions to determine the upgrade scope
Review the planning decisions and related information in the table to plan the upgrade scope and decide whether to deploy new components.
Planning decision | Details |
|---|---|
Can I upgrade just the platform components? | No. You cannot upgrade only the platform components while upgrading BMC Helix Service Management to version 25.3.01. To use only the platform components, you can switch to CORE deployment mode after the upgrade. For information about the deployment modes and transitioning to the CORE mode deployment, see Transitioning between deployment modes. |
Can I upgrade just the applications? | No. You must upgrade the platform to upgrade the applications. |
| Can I minimize my environment footprint and choose to use only the platform? | Yes. You can minimize the footprint of your BMC Helix Service Management environment by upgrading BMC Helix Service Management to version 25.3.01, and then transitioning to the CORE mode deployment. The CORE mode deployment loads only the required platform components into memory only the services you actively use. You can reduce memory and CPU consumption by not starting unused processes and not loading unused metadata and application bundles. |
| Can I minimize my environment footprint and choose to use only BMC HelixGPT? | Yes. You can upgrade BMC Helix Service Management, and then transition to the CORE mode deployment of BMC Helix Service Management. While transitioning, select the CORE deployment mode and the BMC HelixGPT option. |
