Migrate Casino Application Environments with Zero Downtime
A casino manages all aspects of its business (gaming, hotel operations, restaurants, etc.) on HPE NonStop systems. As part of a major upgrade, the casino developed several new applications, restructured its databases, and changed the schema of the Enscribe files and SQL tables.
The casino needed to implement the new applications and database formats in a new platform environment. The casino required 24/7 application availability and could not accept a moment of downtime during the migration.
- Use HPE Shadowbase Zero Downtime Migration (ZDM) to create, synchronize, and test the new application and database environment
- Migrate users to the new environment while keeping the old and new environments in-sync with application services available while the migration takes place

- Maintained revenue and ensured zero loss of service during the upgrade
- Avoided a high risk “big-bang” approach, scaling up the new environment’s load over time (see steps 1-4)
