    Cloud Migration Excellence: Oracle Database Transformation

    RWE Supply & Trading (RWEST)

    Executive Summary

    RWE's Supply and Trading division embarked on an ambitious digital transformation as part of its 'Lead in Cloud' initiative. The challenge: migrate over 20 mission-critical Oracle databases to the cloud while maintaining 24/7 uptime for global trading operations.

    Thriveways delivered a fully automated migration framework that not only met these objectives but exceeded expectations, cutting migration times in half while achieving zero data loss across all migrations.

    The Challenge

    RWE's Supply and Trading division faced several critical challenges with their existing database infrastructure:

    • •Manual, Error-Prone Process: Database migrations required extensive manual intervention, leading to prolonged downtime and increased risk of human error
    • •Cost Burden: Over 100 expensive Oracle licenses tied to on-premises infrastructure, plus significant data-center overhead
    • •Dependency on Offshore Support: Required a dedicated support team in India to maintain the existing system, creating timezone and communication challenges
    • •Performance Constraints: Legacy infrastructure limiting application response times and overall system performance
    • •Mission-Critical Operations: Any downtime could impact global trading operations, making zero-data-loss migrations essential

    Our Solution

    Thriveways designed and implemented a comprehensive automated migration framework that transformed the entire process:

    Automated Migration Framework
