SKIZCorp's Perspective: Incremental system upgrades can be a cost-effective solution for organizations with budget constraints. By maintaining legacy systems alongside modern architectures, ongoing innovation is possible while evaluating both systems. Conducting back development can enhance security practices for modern architectures and improve legacy systems through assessments. Gradual migration to modern architectures helps identify discrepancies while allowing for a graceful fallback process. While this approach may not be suitable for all organizations, temporary complexity is inevitable, and improvements may require some setbacks. However, it helps preserve respect for existing investments.
