what we modernize: core legacy services

Database Optimization & Performance Tuning

We reengineer and streamline your database infrastructure for speed and scalability. Whether you’re running MS SQL, MySQL, PostgreSQL, or NoSQL systems like MongoDB or Elasticsearch, we reduce data redundancy, normalize schemas, and enable smooth transitions between relational and non-relational environments. The result? Faster queries, reduced costs, and scalable architecture.

Cloud Migration & Environment Efficiency

Evinent handles complete migration from legacy on-prem systems or outdated cloud setups (e.g., IIS, physical servers) to modern platforms like AWS, Azure, or Google Cloud. We support everything from lift-and-shift rehosting to full rearchitecting into containerized, cloud-native ecosystems, always focused on reliability, cost-efficiency, and elasticity.

Legacy Application Redevelopment

Outdated CRM, ERP, or industry-specific tools slowing you down? We refactor and rebuild legacy apps, modernizing outdated ASP.NET, WPF, or Windows Forms solutions into .NET Core, MAUI, or Blazor-based environments. We also break down monolithic apps into scalable microservices and redesign UX/UI for today’s users.

Code Modernization & Tech Upgrades

Our team audits and refactors old codebases in C#, VB.NET, and JavaScript, updating them to cleaner, more efficient structures using TypeScript, React, Angular, or the latest .NET stacks. This makes your software more secure, testable, and easier to maintain - with built-in readiness for future growth.

Infrastructure Modernization

Need to reduce infrastructure spending or improve uptime? We help businesses transition from legacy hosting environments (IIS, physical servers, costly clouds) to flexible, high-availability infrastructure with smart autoscaling. We also help switch between cloud providers or move to hybrid/on-prem setups where needed.

Development Process Optimization

Legacy systems often suffer from outdated dev cycles. We help upgrade your development processes with CI/CD pipelines, DevSecOps tools, and intelligent quality checks using platforms like Azure DevOps, SonarQube, Playwright, and Veracode, eliminating bottlenecks and improving team velocity.

Software Platform Transformation

We help tech-driven companies rebuild aging core systems, replatforming Windows-based solutions to hybrid, web-first environments. We refactor legacy logic, introduce modular architecture, and migrate systems into modern containers or microservices without interrupting daily operations.

Enterprise Digital Transformation

Beyond upgrades, we help enterprises shift toward API-first, integration-friendly systems. Whether it's overhauling monoliths, redesigning customer portals, or enabling AI-readiness, we build resilient foundations for innovation, automation, and long-term market leadership.

FAQ
Still have questions?
What is legacy system migration?

Legacy system migration involves transferring outdated systems, applications, or infrastructure to modern platforms, technologies, or architectures. This process enhances system performance, scalability, security, and interconnection capabilities while addressing limitations associated with older systems.

Why is migrating legacy systems important for businesses?

Migrating legacy systems is essential to stay competitive in today’s fast-paced digital world. It helps businesses reduce operational costs, improve system reliability, enhance security, and integrate with modern technologies like cloud computing or AI. Moreover, it guarantees compliance with current industry standards and improves the overall user experience.

How do I know if my business needs legacy migration?

Signs that your business needs legacy migration include:

  • Frequent downtime or slow system performance.
  • High maintenance costs for outdated technologies.
  • Incompatibility with modern tools or platforms.
  • Security vulnerabilities due to older software.
  • Inability to meet growing operational demands.

If your system hinders your business growth, it’s time to consider migration.

Will my data remain secure during migration?

Absolutely. Data security is a top priority during legacy migration. Expert teams implement robust encryption protocols, access controls, and thorough testing to data integrity and prevent unauthorized access.
