Frequently Asked Questions
Have questions? We have answers. Here are some common queries about legacy modernization.
The first and most critical step is a thorough assessment. Before any code is touched, you need a clear, data-driven understanding of your current system's architecture, code quality, technical debt, and business value. Our AI-Powered Portfolio Assessment provides this clarity, forming the foundation for a successful, low-risk modernization strategy.
We use proven, risk-averse methodologies like the Strangler Fig pattern. Instead of a "big bang" migration, we incrementally replace parts of the legacy system with new services. The old and new systems run in parallel, and traffic is gradually shifted over. This ensures zero downtime for critical functions and allows for a safe, controlled transition.
No, moving to the cloud (rehosting) is just one possible strategy and often only the first step. True modernization is about re-architecting your application to be cloud-native. This means designing for scalability, resilience, and agility using concepts like microservices, containers, and serverless computing to unlock the full potential of the cloud and your business.
ROI is measured across several key areas: 1) **Cost Reduction:** Lowering infrastructure costs (hardware, licensing, data center fees) and operational overhead. 2) **Increased Agility:** Measuring the reduction in time-to-market for new features (developer velocity). 3) **Risk Mitigation:** Quantifying the cost of potential outages, security breaches, or compliance failures associated with the old system. 4) **Revenue Enablement:** Attributing new revenue streams made possible by the modernized platform's capabilities.
This is a very common challenge. Our AI-powered analysis tools are specifically designed for this scenario. They can reverse-engineer business logic directly from the source code, map complex dependencies, and create the documentation and architectural understanding needed to plan the modernization project effectively, even when institutional knowledge has been lost.
