Chapter 4. Infrastructure changes by deployment type

You can review the infrastructure changes required when upgrading to Ansible Automation Platform 2.6. The infrastructure changes vary depending on your current version, deployment method, and target topology.

  • RPM and Operator-based deployments: Upgrade directly from version 2.4 or 2.5 to 2.6
  • Container-based deployments: Upgrade from version 2.5 to 2.6 (upgrades from 2.4 are not supported)

Each deployment type section includes topology diagrams, infrastructure requirements, and configuration examples to help you plan your upgrade.

4.1. RPM-based deployments

The following sections describe the tested infrastructure changes for RPM-based deployments. For step-by-step upgrade instructions, see RPM upgrade.

You can upgrade your 2.4 single automation controller node deployment to a 2.6 growth topology. This section outlines the infrastructure changes, requirements, and an example inventory for upgrading.

You can upgrade your 2.5 growth topology to a 2.6 growth topology on OpenShift Container Platform. The topologies are the same between Ansible Automation Platform 2.5 and 2.6.

For more information about the growth topology infrastructure requirements and configuration details, see the Operator growth topology section of Tested deployment models.
