Migrate Casino Application Environments with Zero Downtime

Situation

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 their databases, and changed the schema of their Enscribe files and SQL tables.

Problem

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 any downtime during the migration.

Solution

  • 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 synchronized with application services available while the migration takes place
