Legacy Software Audit and Assessment Services

A thorough examination of the software’s programming languages, frameworks, databases, and other tools is a cornerstone for further analysis. This step helps you to:

• Understand the relevance of the current tech stack, comparing it with renewed goals and modern technologies,
• Identify technical debt and obsolete technologies posing risks or operational hurdles,
• Learn whether this tech stack can potentially handle the upcoming changes.

This evaluation will show the most effective ways to implement modern technologies in the current stack for better performance and maintainability, or completely replace it.

Often, it’s not enough to analyze the system’s basic structure in terms of modularity, scalability, and integration capabilities. We delve deeper to evaluate non-functional qualities, as their inconsistencies affect the whole system.

In particular, cooperative workshops determine and rank the system’s non-functional requirements according to the ISO/IEC 25010 standards. However, proven techniques help to:

• Assess the current architecture’s resilience to accommodate upcoming additions or integrations.
• Determine if the architecture can grow with the company and adapt to its changing needs.
• Identify any bottlenecks or architectural defects that can impair flexibility or performance.

As a result, the audit addresses unique challenges posed by legacy systems and shows how potential modifications may affect the whole product.

Define how a product should create value, who it serves, which problems it should solve first, and how those priorities translate into a practical delivery roadmap. Devox Software shapes positioning, target users, core use cases, feature priorities, technical feasibility, delivery sequencing, and the metrics used to evaluate progress.

The goal is to give product and engineering teams a shared direction before major development investment begins, reducing rework and helping leadership make clearer decisions about scope, timing, and next-stage growth.

Hardware and software environments are closely intertwined. This concerns servers, databases, networks, and cloud services — everything impacts the performance. That’s why we additionally review the following:

• Resource consumption inefficiencies and possible cost-cutting measures,
• Advantages and viability of moving to cloud infrastructure,
• Redundancy, failover, and backup strategies,
• Cloud migration feasibility (for IaaS/PaaS/SaaS),
• Infrastructure that can withstand failures and bounce back fast.

As a result, we recommend particular tactics or solutions to ease the transition when required.

Legacy software frequently has an overly large codebase that needs to be reviewed and refactored regularly. That’s why we use SonarQube, ESLint, PMD, complexity analyzers, and custom linters to examine the software’s source code. They help to:

• Find errors and bugs in the code, as well as the room for code simplification,
• Assess the overall code’s readability and extensibility,
• Identify areas for improving code efficiency.

When updating historical systems, security is often a weak link in safeguarding private information and guaranteeing legal compliance. We assess the system against OWASP ASVS and the regulations that apply to you (PCI DSS, HIPAA, GDPR, CCPA), and map controls to ISO 27001 where relevant.

Following an audit, we present a viable and multi-layered action plan for enhancing security protocols, protecting your system and automating data security protocols, and preventing data leakage.

Static evaluation is not complete without a proper performance audit of the system under various circumstances. That’s why we use manual and automated testing:

• Load Testing: Using JMeter, k6, we determine how well the application manages large numbers of users or data
• Stress Testing: We evaluate how the system behaves under extreme load

As a result, we understand which aspects should be improved to increase efficiency and speed. This ensures that your legacy software can withstand future growth upon modernization.

Old systems are difficult to combine smoothly with contemporary platforms and apps. Many outdated systems use proprietary protocols that prevent seamless data sharing. Thus, through an analysis of the data formats, middleware communication protocols, and APIs in use, the audit determines the scope of these interoperability problems.

Moreover, we evaluate your system’s cloud compatibility, pointing out obstacles and describing migration options, such as re-architecting, re-platforming, or lift-and-shift. Together, these findings show whether be integrated with contemporary technologies or replaced.

Legacy database systems often store large volumes of data in obsolete formats, making it difficult to derive valuable historical data for analysis. That’s why, through ETL tool assessments, schema validators, and data lineage mapping, we cover the following aspects of data management:

• Data schemas and storage formats
• Data quality, integrity, and archival procedures
• Database migration readiness and transformation needs
• Adherence to data governance laws

Thus, a comprehensive approach opens the way for possible database migration and further data-driven decision-making.
