Structured process we follow for legacy system modernization

services

Discovery & assessment

Our process begins with a comprehensive assessment of your legacy application landscape. We analyze the architecture, codebase, third-party dependencies, data structures, and integration points. This phase helps us identify technical debt, system bottlenecks, and business-critical components. By aligning technical findings with business priorities, we gain a clear understanding of what to modernize, why it matters, and what success should look like.

Modernization strategy definition

Based on the insights from the discovery, we define the right modernization strategy. Depending on the application’s complexity, value, and risk profile, we recommend the most appropriate path, whether it’s rehosting (lift-and-shift), refactoring specific modules, rearchitecting to microservices, or rewriting the entire system. We also finalize the technology stack, architecture patterns, and cloud environments suited for your business needs.

Pilot implementation

Before a full-scale rollout, we implement a pilot project for one of the critical modules. This allows us to validate the modernization approach in a controlled environment, uncover potential integration or performance issues, and refine the migration plan based on real-world results. It serves as a proof-of-concept that reduces risk and builds stakeholder confidence.

Modular migration & development

Once the pilot is successful, we move into the phased modernization of the remaining system. We follow a modular approach to refactor or rebuild application components incrementally. At the same time, we redesign the front end for modern devices, migrate databases to scalable platforms, and build secure APIs for interoperability. This approach helps us deliver value faster while keeping the core business running.

Quality assurance & testing

Throughout development, we maintain rigorous quality control. Our QA teams conduct automated testing, performance benchmarking, and thorough security checks to ensure the modernized system is stable, scalable, and secure. We also involve users for acceptance testing to validate business workflows and usability before deployment.

Deployment & change management

Once the system is validated, we transition it to production using CI/CD pipelines for smooth, zero-downtime deployment. We support your team with documentation, training, and change management strategies to ensure seamless adoption. We also assist in decommissioning outdated components to simplify the IT environment.

Monitoring, optimization and support

Post-deployment, we closely monitor system performance, usage patterns, and feedback to fine-tune the application. Our support team ensures the system runs reliably and is optimized for cost and performance. We continue to enhance features and provide ongoing maintenance based on SLA commitments, ensuring long-term success.

Frequently asked questions (FAQs)

What is software modernization & why is it important?

Software modernization is the process of updating, refactoring, or replacing outdated software applications to enhance their functionality, performance, security, and alignment with current technology trends.

It is crucial to keep applications competitive, secure, and efficient in a rapidly evolving digital landscape. It also reduces maintenance costs and extends the lifespan of applications.

You may look for signs such as:

◉ Performance Issues: If your software experiences frequent crashes, slow response times, or struggles to handle increased workloads, it may be a sign that modernization is needed. Modernization can optimize performance and responsiveness.

◉ Security Vulnerabilities: Outdated software can have security vulnerabilities that put your data and systems at risk. Modernization can include security enhancements to ensure your applications are protected against evolving threats.

◉ Maintenance Costs: If maintenance costs are becoming a significant burden due to the need for constant bug fixes and updates, modernization can lead to reduced maintenance costs over time.

◉ User Complaints: Frequent user complaints about usability, outdated interfaces, or missing features are indicators that your software may need a revamp to enhance the user experience.

◉ Scalability Challenges: If your software struggles to scale with growing data volumes or increasing users, modernization can make it more adaptable and efficient.

◉ Integration Difficulties: Inability to integrate with newer systems or third-party services can hamper your business processes. Modernization can enable seamless integration with modern technologies.

To kickstart the modernization process, we will need several insights such as objectives, business requirements, budget, timeline and more, to ensure a successful modernization partnership.

For deeper details, it would be great to connect with your technical personnel and developers who could provide assistance, for a thorough overview. For more information, connect with our experts in a free consultation session.

In general, the cost of software modernization varies widely depending on factors such as the scope of the project, the complexity of the software, and the extent of changes required. It’s essential to conduct a thorough assessment and define clear project goals to determine costs accurately.

Timelines vary based on the complexity, size, and chosen modernization strategy. A straightforward rehosting might take weeks, while re-architecting or rebuilding a large system can take several months. A discovery phase helps determine accurate timelines.

It depends on your existing system’s architecture, code quality, and alignment with current business needs. If the core logic is still valid, modernization might be more cost-effective. However, if the system no longer meets your functional or performance requirements, a complete rebuild may be necessary.
