Virtual Machine Software Testing for Upgrade Validation

The patent creates virtual copies of customer server environments using configuration data from actual installations. These virtual environments replicate the unique characteristics, customizations, and data structures of real customer systems, enabling comprehensive compatibility testing without requiring access to live production systems. The copying principle allows multiple test scenarios to be executed in isolated virtual instances.

The testing system segments the complex testing process into distinct phases: environment replication, upgrade simulation, and compatibility validation. Configuration data is segmented into extractable components that can be independently processed. This segmentation manages complexity by breaking down the monolithic testing task into manageable, automated steps.

The virtual environment templates serve multiple functions: they can be instantiated repeatedly for different test scenarios, shared across multiple testing operations, and reused after validation. A single configured virtual environment can test multiple upgrade paths and compatibility scenarios, maximizing resource utilization while maintaining high testing productivity.

Virtual environments are pre-configured with customer-specific data and settings before actual upgrade testing begins. This preliminary setup allows the environments to be ready for immediate parallel testing execution, improving throughput while avoiding redundant resource consumption during the actual testing phase.

The patent introduces virtual environments as an intermediary layer between customer data and the testing process. Customer configuration data is extracted and used to build isolated virtual instances that replicate production environments. This intermediary structure enables accurate automated testing with real customer data while maintaining security through isolation, allowing validation without direct access to live systems.

Instead of directly accessing or manipulating live customer data, the system creates accurate copies in virtual environments. These copies preserve the structural and functional characteristics of real customer installations for high-fidelity testing, while the copying process itself provides a security boundary that prevents unauthorized access or data breaches.
