FAQ’s Related to Legacy Application Modernization
Application modernization is complex, especially with deeply embedded legacy systems. Common challenges include outdated code, minimal documentation, and obsolete technology dependencies.
- Without the right strategy, modernization efforts can pose significant risks to stability and performance.
- Maintaining business continuity during migration or refactoring requires detailed planning and technical expertise.
- Integrating modern applications like microservices and cloud platforms can introduce security and interoperability concerns.
At Telliant Systems, we combine deep technical know-how with a business-first approach to ensure smooth, low-risk modernization.
Mainframe and legacy applications are still prevalent in many industries, including financial services and healthcare. Not only is it hard to find qualified resources who can develop in legacy technologies, it is also challenging for these systems to connect to modern technologies and meet user expectations. We excel in modernizing applications to fit today’s advanced environments.
- Convert software written in legacy languages such as COBOL, RPG, Assembler, C/C++ to a modern technology stack running in a cloud-based architecture.
- Revamp user interface style guides to meet today’s standards and the needs of modern applications for stability, scalability and higher levels of security.
- Refine workflows to reduce clicks and enable seamless user experiences and modern user interactions.
- Open access to data for integrating with new platforms and architecture to optimize digital applications.
Some of the key aspects and approaches of legacy app modernization includes, cloud migration, rehosting/replatforming, refactoring, app integration, app containerization, UI/UX modernization, technology modernization, software modernization, app testing, security and compliance.
At Telliant, software modernization means taking your existing, often outdated, applications and reshaping them to meet today’s technology and business needs. This could involve reworking the code, redesigning the user experience (UI/UX), or shifting the infrastructure to the cloud. The goal isn’t to start from scratch, it’s to improve performance, security, and flexibility while preserving the systems that still serve your business. We help you move from legacy limitations to a more modern, scalable, and efficient foundation.
Yes, AI can be integrated into legacy systems, and at Telliant, we make that transition seamless. While older applications may not be AI-ready, we enable smart functionality by extending your system’s capabilities through modern integration layers. Our approach allows legacy platforms to access AI-driven insights, such as automation, forecasting, or data classification, without disrupting core operations. This way, you can enhance the value of your existing systems while gradually embracing intelligent technologies.
