Upgrade the AIQ Controller and Test Nodes

Use this article to plan and validate an AIQ Controller and Test Node upgrade with backups, compatibility checks, and post-upgrade smoke tests.
What changed in this article
Rewrote the title with current AIQ Controller and Test Node terminology.
Added upgrade planning checks for backup, version compatibility, maintenance window, Test Node sequencing, browser/runtime dependencies, and rollback readiness.
Added post-upgrade validation for login, node heartbeat, scenario execution, logs, and reports.
Validation workflow
Back up required configuration and data, confirm target version compatibility, and schedule a maintenance window.
Upgrade the controller and Test Nodes according to the approved release procedure and verify services start cleanly.
Run smoke tests covering login, node heartbeat, one small execution, report access, and integration checks.
Review note: This page now emphasizes controlled upgrade validation instead of only procedural upgrade steps.
