Service Overview

Legacy System Assessment and Reverse Engineering

We provide a comprehensive assessment of legacy systems, encompassing software, infrastructure, and databases, evaluating technical performance, security levels, operational costs, and their ability to support both current and future business requirements.

Based on the assessment results, we present clear strategic options, including system re-engineering, modernization and enhancement, or full replacement, aligned with business priorities and growth plans.

The service includes analysis of database structures and data models, tracing transaction flows, mapping critical processes, and identifying technical dependencies, along with detailed technical documentation that enables teams to make informed decisions and move forward with confidence and security.

Through this service, we aim to improve system reliability, enhance cybersecurity, increase operational agility, and reduce maintenance costs, enabling the organization to transition smoothly to more efficient and dependable modern technologies.
