Hi everyone,

I am planning to upgrade Red Hat Ansible Automation Platform from version 2.4 to 2.5.

Current environment:

• 2 x Controller nodes (clustered)
• 1 x Automation Hub node
• 2 x PostgreSQL clusters (replicated):
  • db-controller (used by controller nodes)
  • dbhub (used by automation hub)

AAP 2.5 introduces the Gateway component, which I understand is required.

Could anyone guide me with a clear step-by-step upgrade procedure for this setup?

I am looking for:

• The exact upgrade sequence (gateway, controller, hub, database)
• Required inventory file changes
• Pre-upgrade checks and backup recommendations
• Post-upgrade validation steps
• Any common issues or pitfalls

I would really appreciate detailed, practical guidance based on real experience.

Thanks in advance!
