Our Modernization Process

Legacy System Audit & Readiness Assessment

Modernization Readiness Assessment

When we start the new project, the first thing we do is creation of modernization readiness report. This helps us understand the project needs and its alignment with business goals. The goal is to see how the product works today and what must be addressed to ensure stability and growth.

Evaluation of Historical and Current System’s State

Each system has a history behind. We look at how the system was built and why it was done in that manner. Then we access the existing stage of the project, e.g documentation, functionality, and team roles. The main goal is to discover how the system is maintained, where knowledge gaps exist, and whether daily processes support the project goals.

Recommendations and Roadmap Creation

Based on the findings, Corsac legacy software modernization company creates a detailed report with clear short-term and long-term modernization steps that would cover future development. Every project is absolutely unique, and so are our legacy system modernization services.

Recommendations and Outcomes

Before jumping into the modernization stage itself, you will get a clear identification of the current software’s state, a detailed report with the assessment results, a list of improvements, and prioritization of modernization directions. This is how we keep project transparency and well-informed decisions.

Seamless Modernization with Our End-to-End Process

Step 1. Discovery & Technical Analysis

Deep understanding of both tech base and business challenges is the key to successful modernization. We thoroughly assess your current code quality, architecture, integrations etc. — alongside your business processes and needs.

Step 2. Strategic Modernization Planning

Audit Components

Legacy System Audit Services We Provide

Audit of legacy systems shows how outdated systems stagnate business operations. Our legacy application modernization company highlights the real risks and lays foundation for well-informed modernization decisions.

Compliance & Regulatory Audit

We evaluate your system compliance with key industry standards (HIPAA, GDPR, SOC2, PCI, ISO). We highlight compliance blind spots, old data practices, and architectural issues that create legal and operational risk.

Functionality & Workflow Audit

We audit your system's slow spots, worn-out features, and places where it doesn’t match market expectations and cannot support current business processes and future goals.

Architecture & Scalability Audit

We review the structure of your system to expose hidden coupling, bottlenecks, and design debt that slow cloud adoption, CI/CD, APIs, and new features adoption.

Security & Vulnerability Audit

We assess authentication, data use, and logging to uncover flaws from outdated code and infrastructure that may expose you to data breaches or loss.

Code Quality & Maintainability Audit

We analyze code hygiene, from duplication to missing tests, to show why fixes drag on, bugs return, and which refactoring efforts deliver real ROI.

Why Choose Corsac As Your Modernization Partner?

Modernization is our core specialization

We aren’t a full-stack agency. We’ve built our team, processes, and tech strategy specifically to tackle legacy issues and help mid-market players scale and innovate.

Integration vs. Disruption

We integrate with your workflows, minimizing interference with your developers. While utilizing your Git, CI/CD, and tools, we operate independently, letting your team focus on their work.

Identification of hidden expenditures

Your aging system drains your business resources through slow hiring, security gaps, and delayed launches. We reduce these “dark tech debt” losses before they impact your revenue.

Respect for Existing Architecture and Leadership

We treat your system efficiently: evolve the functioning parts and replace only the ones that require change.

Fighting Tech Stagnation

Modernization efforts will be ineffective if the core issue is institutional rigidity. We reveal hidden limits and help grow with flexibility.
