VELO - Agentic AI for Code Modernization
Powered by Microsoft Azure AI Foundry

Agentic AI for Legacy Code Modernization

VELO orchestrates a team of specialized AI agents to transform your legacy applications into modern Blazor and Azure solutions. Unlike general-purpose AI, each agent is purpose-built for its phase of the modernization lifecycle, delivering production-quality code that compiles and runs.

Why General AI Tools Fall Short

General-purpose AI can write code, but legacy modernization requires domain expertise that ChatGPT and Copilot were not built for.

Undocumented Logic

Legacy code is often tightly coupled with decades of undocumented business rules embedded in VBA macros, stored procedures, and form events.

Data Fragmentation

Desktop databases are local, unencrypted, and disconnected. Schema mapping to Azure SQL or Cosmos DB requires semantic understanding, not just syntax translation.

UI Translation Gap

Backend developers struggle with modern CSS/HTML. Translating Access Forms or WinForms to responsive Blazor components requires specialized UI agents.

Purpose-Built AI Agents

VELO deploys a multi-agent system built on Azure AI Foundry Agent Service. Each agent is specialized for a specific phase of modernization.

🔍

Scout Agent

Scans your legacy application and builds a complete understanding of its structure.

  • Identify tables, relationships, complexity
  • Map form dependencies and data flows
  • Generate modernization metrics

Architect Agent

Proposes the optimal modern architecture based on your application's requirements.

  • Blazor Server vs WebAssembly
  • Entity Framework Core mapping
  • Azure SQL / Cosmos DB strategy

Translation Agent

Converts legacy logic into modern C# and Razor syntax with semantic accuracy.

  • VBA/SQL to C# conversion
  • Forms to Blazor components
  • Modern .NET patterns
4

Quality Agent

Validates output against original behavior and generates comprehensive tests.

  • Automated unit test generation
  • Parity verification
  • Azure DevOps integration

How VELO Works

From legacy input to production-ready output, VELO orchestrates the entire modernization workflow.

1

Upload & Scan

Upload your legacy application. The Scout Agent analyzes structure, dependencies, and complexity metrics.

2

Architecture Proposal

The Architect Agent recommends project structure, data access patterns, and Azure deployment strategy.

3

Code Transformation

The Translation Agent converts legacy logic to C#, forms to Blazor components, and data access to Entity Framework.

4

Quality Assurance

The Quality Agent generates tests, verifies parity with original behavior, and validates compilation.

5

Engineering Ready

Download code that compiles and runs. Human engineers then stabilize to production quality.

OrderService.cs
// Generated by VELO Translation Agent
public class OrderService : IOrderService
{
  private readonly AppDbContext _context;

  public async Task<List<Order>>
    GetOrdersByCustomerAsync(int customerId)
  {
    return await _context.Orders
      .Where(o => o.CustomerId == customerId)
      .Include(o => o.LineItems)
      .OrderByDescending(o => o.OrderDate)
      .ToListAsync();
  }
}

Production-Ready Modern Stack

VELO delivers applications built on Microsoft's latest technologies with enterprise security by default.

Technical Questions

Common questions about VELO's architecture, capabilities, and output quality.

Engineering Ready means the generated code compiles and runs. It is not production-ready out of the box. Human engineers then stabilize, optimize, and polish the output to production quality. This hybrid approach ensures you get the speed of AI with the quality of human engineering.
The Scout Agent deconstructs legacy code into structured logic maps using LLMs. Complex VBA, stored procedures, and form events are analyzed semantically, not just syntactically. For edge cases, VELO flags areas requiring human review rather than guessing.
VELO automates schema mapping from local databases to Azure SQL or Cosmos DB with 100% data integrity. Your data is never used for model training. All processing happens within Azure with strict data isolation and zero-data retention policies.
VELO supports modernization from VB6, VB.NET, C# WinForms, MS Access, WebForms, PowerBuilder, and Clarion. Output targets include Blazor (Server or WebAssembly), Azure SQL, Cosmos DB, and Azure App Service with Entra ID authentication.
VELO combines deterministic transformation with generative AI. The deterministic engine handles core logic translation with compiler-grade precision. Generative AI is used for analysis, documentation, and test generation under strict guardrails. Complex transformations can be reviewed before being committed.
