Case Study: ANZ achieves 640 hours of testing saved and zero downtime in data center migration with ScriptRock

ANZ - Customer Case Study

ANZ, one of Australia’s Big Four banks, needed to consolidate an acquired insurer’s outsourced data center into its centralized facilities. The migration touched 160 servers, 180+ applications and over 80 TB of data, had to occur over a single weekend with only a 4‑hour testing window, and required near‑zero customer‑facing downtime.

By using ScriptRock to capture live configurations and generate executable, human‑readable tests, the team automated verification across every node and removed manual guesswork. Manual testing that was estimated at 640 hours was reduced to 30 minutes during the go‑live, eliminating downtime, reclaiming 3.5 hours for other tasks, and delivering substantial cost savings and avoided engineering and outage expenses.
