At Incora, we modernize legacy applications without disrupting operations — reducing technical debt, improving performance, and enabling long-term growth through modern architectures, cloud platforms, and intelligent automation.

Application Modernization Services We Offer

Our legacy application modernization services address both technical limitations and business constraints. We don’t simply replace outdated systems. We enhance how your software supports daily operations, long-term scalability, and evolving business requirements.

Development & Implementation

Support & Consulting

Legacy System Transformation

We modernize monolithic, outdated platforms by restructuring architecture, optimizing codebases, and aligning systems with current business needs. Legacy system modernization improves performance, simplifies maintenance, and enables faster delivery of new features.

Cloud Migration

We migrate legacy systems to AWS, Azure, or Google Cloud using secure, phased strategies. Cloud migration increases scalability, availability, and reliability while improving cost control and reducing dependency on rigid on-premise infrastructure.

Microservices adoption

By decomposing monolithic systems into modular, independent services, we improve system resilience, deployment speed, and scalability. Microservices adoption allows teams to evolve specific components without risking the stability of the entire application.

Modernize Your Legacy Application

When To Consider Modernization?

Legacy application modernization services become critical when existing systems begin to limit growth, increase operational risk, or slow teams down rather than support business goals.

High maintenance costs

Legacy systems often require constant fixes, specialized skills, and outdated infrastructure. Over time, maintenance and support costs grow disproportionately, diverting budgets from innovation and making the system more expensive to keep than to modernize.

Codebase refactoring — reduces technical debt and simplifies long-term maintenance.
Infrastructure optimization — lowers hosting and operational costs
Dependency cleanup — removes obsolete libraries and unsupported components
Support process automation — minimizes manual intervention and recurring fixes

Poor performance and scalability

Outdated architectures struggle to handle growing data volumes, user loads, and new functionality. Poor performance, frequent downtime, and limited scalability directly affect productivity, customer experience, and the ability to support business growth.

Architecture optimization — improves system responsiveness and throughput
Scalability redesign — enables systems to handle growth predictably
Caching and load balancing — reduces latency and stabilizes performance
Performance monitoring — identifies and resolves bottlenecks proactively

Difficulty integrating with modern tools (APIs, cloud, AI)

Legacy systems are often incompatible with modern APIs, cloud platforms, and AI tools. This limits automation, data exchange, and digital transformation initiatives, forcing teams to rely on manual processes or costly workarounds.

API enablement — exposes legacy functionality for modern integrations
Cloud readiness updates — prepare systems for cloud platforms and services
Data integration layers — ensure consistent data exchange across tools
Service decoupling — simplifies connections with external systems

Got Questions? Find Your Answers Here

There are some of the frequently asked questions.

What is legacy system modernization?

Legacy system modernization, also known as IT legacy modernization, is the process of improving outdated software to meet current technical, security, and business requirements. This may involve updating architecture, refactoring code, migrating infrastructure to the cloud, improving integrations, or redesigning user interfaces. The objective is not only to extend system lifespan, but also to reduce technical debt, improve performance, and ensure compatibility with modern tools and platforms.

What are common approaches to modernization?

Common legacy application modernization approaches include rehosting, replatforming, refactoring, re-architecting, and rebuilding. Each method varies in cost, risk, and depth of change. The right approach depends on factors such as system complexity, existing technical debt, business criticality, available budget, and the level of flexibility required for future scaling or integrations.

How long does it take to modernize an application?

The timeline for application modernization depends on the system’s size, architecture, dependencies, and the chosen modernization strategy. Smaller or well-isolated systems can be updated within a few months, while complex, business-critical platforms are often modernized gradually over 6–12 months. Phased implementation helps reduce risk, avoid downtime, and maintain operational continuity.

How can I get started with legacy application modernization?

Getting started typically begins with a technical and business assessment of the existing system. This includes reviewing architecture, dependencies, data flows, performance bottlenecks, and security risks. Based on the findings, a modernization roadmap is created that defines priorities, scope, timelines, and the most appropriate approach, allowing organizations to move forward with clarity and controlled risk.

How much do legacy application modernization services cost?

The cost of legacy application modernization services depends on system complexity, modernization scope, and the selected approach. Incremental modernization usually requires lower upfront investment, while full system transformation involves higher costs spread across multiple phases. In many cases, modernization leads to long-term savings through reduced maintenance, improved efficiency, and lower operational risk.
