Case Study: ANZ Bank achieves zero‑downtime data‑center consolidation and 1,280x faster migration validation with UpGuard

ANZ Bank completes a data center migration in just 48 hours

ANZ Bank, one of Australia’s big four banks, needed to consolidate an acquired insurance provider’s outsourced data center—hundreds of servers hosting critical business functions—into its central data center over a single weekend with virtually no customer‑facing downtime. ANZ engaged UpGuard to address the lack of centralized documentation and to provide comprehensive automated testing and validation for the migration.

UpGuard captured the live environment, transformed configurations into executable documentation, and enabled human‑readable automated tests via its UI, allowing rapid, team-wide validation. Using UpGuard, ANZ migrated and automatically validated 180+ applications and 160 servers, reduced validation time by 99.975% (cutting ~640 hours of manual testing to a 30‑minute run), achieved 1,280x faster testing, and realized an estimated $3M+ in savings while completing the migration with no downtime.
