Our Application Modernization Competencies
Modernization strategy & assessment
System modernization consulting
We thoroughly investigate your legacy application code and infrastructure, mine requirements, and provide detailed guidance on the improvements that can help you derive maximum value from previous investments.
INNERLUXES helps companies revamp business processes for better efficiency, agility, and resilience and achieve higher ROI by evolving and integrating the existing corporate apps or reusing their parts in new solutions.
Application & database transformation
Application conversion and database migration
We revive applications built on legacy languages and platforms — PowerBuilder, Delphi, VB, C++, COBOL, outdated Java and .NET — by converting them to modern programming languages and frameworks. We also migrate databases from legacy or proprietary engines (Oracle, Microsoft SQL Server, IBM Db2, Sybase) to open-source, cloud-optimized database platforms such as PostgreSQL, MySQL, and managed cloud database services. Automated conversion toolkits handle the bulk of the work, while our engineers take on complex logic and custom features through targeted manual tuning.
Application & database reengineering
We improve the internal structure, code quality, and data models of existing systems without changing their overall architecture. This includes:
- Adding new features.
- Optimizing SQL, stored procedures, and data access layers.
- Improving maintainability, performance, and stability.
- Web and mobile enablement.
- Improved look and feel.
- Simplified and less costly maintenance and updates.
- DevOps and CI/CD enablement.
Application & database rearchitecting
We execute deep redesigns of application and database architectures to improve scalability, resilience, security, and integration readiness. Typical transformations include:
- Monoliths to modular service-oriented architecture (SOA), microservices, or serverless implementations.
- Single-node databases to distributed or managed cloud databases.
- Architectures optimized for cloud elasticity and high availability.
Data modernization
We revamp your approach to data management and upgrade data systems to set up fast, scalable, and secure data analytics within your company. We implement self-service BI and apply data visualization techniques so you can generate on-demand reports and grab enlightening data insights.
Cloud enablement & runtime modernization
Depending on the system and business needs, INNERLUXES offers one of three ways to the cloud: rehosting, replatforming, or a cloud-native implementation.
Application containerization
We can package your applications or their components into containers, isolating them from each other at the operating system level.
Containerization means:
- Fewer resources required to run.
- Easier scalability.
- Simplified movement across different environments.
- CI/CD practices enablement.
Experience evolution, trust, risk & compliance
Mobile and cross-platform compatibility
Our designers and software engineers help businesses ensure their software offers seamless experiences across platforms and devices. We thoroughly review your solution to identify potential compatibility issues — functionality and display problems, security conflicts — and provide recommendations for remediation.
Regulatory compliance
Our compliance consultants, cybersecurity experts, and software engineers help ensure that your apps comply with applicable laws and regulations — HIPAA, PCI DSS, GDPR, and others. They assess your software and its design, development, testing, and deployment processes, identify gaps in your compliance program, and develop a customized plan to address them.
Security enhancement
An service provider, INNERLUXES offers the skills and knowledge of top experts to assess and improve the security of web, mobile, and desktop applications and find ways to enhance data protection.
Accessibility compliance
We help businesses ensure their software is accessible to all users, including those with disabilities. Our team has experience with ADA, Section 508, WCAG, and other standards. We assess your software and help remediate accessibility issues — lacking keyboard accessibility, insufficient color contrast, forms that are not properly labeled, no alternative text and transcripts for images, video, and audio.

What every migration delivers

What each migration path adds
|
When businesses come to us for legacy software modernization, we often recommend considering cloud migration as part of the project. At this point, moving to the cloud is usually the most rational thing to do: you cut operational costs, raise app availability, and gain access to cloud-dependent technologies such as AI automation and data science. To make cloud migration fast and secure, our team divides legacy software into manageable parts and ensures a gradual transition from one stable state to the next. We also offer clients a pilot migration first — it helps assess the viability of the chosen approach and make the required tweaks cost-efficiently and risk-free.

Our 4-Step Application Modernization Strategy
Each legacy app gets a unique modernization strategy. However, we follow a structured process to save time on organizational matters.
1
Assessment
We audit the code, architecture, data model, integrations, and infrastructure of the legacy app, mine business rules where documentation is missing, and quantify technical debt.
2
Strategy and feasibility study
We compare modernization paths — rehost, replatform, refactor, rearchitect, rebuild — and deliver a feasibility study with expected gains, cost estimates, and a risk analysis.
3
Incremental implementation
We split the app into independent, loosely coupled parts and modernize them one at a time, keeping the system in a working state between releases so business operations never stop.
4
Verification and continuous evolution
We run regression, performance, and security testing on every modernized module, monitor the app in production, and plan the next increment of support and evolution.
Application migration to cloud scenarios
- Application re-hosting. We move the application from the on-premises or old cloud infrastructure to the new cloud (AWS or Azure). This is a fast and simple migration option that enables DevOps and ubiquitous access and optimizes the usage of hardware resources; it also streamlines more advanced modernization later. However, re-hosting offers only limited cloud-driven benefits in terms of app resilience, performance, and scalability.
- Application re-platforming. We complement moving the application to the cloud with small modifications and upgrades in code that bring more advanced cloud capabilities — improved performance, scaling, fault tolerance — to the application.
- Cloud-native implementation. We transform the app architecture (e.g., split it into web services or microservices) to make it withstand dynamic load and performance requirements and allow partial updates, technology mix, and shared platform usage.

Answering Frequent Questions about Application Modernization
What is the biggest factor in deciding to start the modernization process for an application?
Cost is the overriding factor prompting app modernization. Companies can live with legacy apps, but the maintenance and evolution cost will be high. As legacy apps are rigid, a support team puts in significant time and effort to deliver new features, and some changes are not even possible. The backlog keeps mounting, just like your irritation and the feeling of irrational spending. App modernization is an investment that pays back after the first year of reduced maintenance costs.
Is it possible to modernize a legacy app with no detailed documentation (functional specifications)?
Yes. In this case, INNERLUXES mines the business rules from the existing application code and documentation and investigates code dependencies and component integrations. We are also ready to cooperate with your in-house IT team, third-party vendors, and other parties knowledgeable of the application to speed up the process.
How can I be sure that the modernized app will bring the expected results instead of only wasting the company's time and resources?
We rely on robust risk management practices and start with an in-depth assessment of your legacy system, focusing on technical, business, and economic considerations. Before starting any project, we prepare a comprehensive feasibility study report with estimated gains and risk analysis to help you make a well-informed decision on the legacy app's future. To make modernization as transparent and manageable as possible, our software engineers split legacy apps into several independent modules so that changes are introduced quickly and incrementally.
Can we modernize legacy applications without operational downtime?
Yes. We conduct thorough testing and continuous monitoring of the modernized app modules to make sure they run as expected and don't disrupt your business processes.
Is it possible to avoid a long freeze-up of the apps during modernization?
Yes. For this, we split applications into several independent, loosely coupled parts (e.g., microservices) to introduce the required changes fast and incrementally.
