AI-Native Legacy Modernization Platform

Understand your Legacy System before you rewrite it.

EltegaAI Legacy Modernization Platform Interface

EltegraAI extracts business logic from your enterprise legacy system and turns it into a specification — so you start with a contract instead of a guess.

6 of 10 spots left in June

70% of modernizations stall. Yours is about to hit the same 3 walls…

The knowledge cliff:

Your engineers hold the system in their heads. Documentation is stale or missing, and the rest of the team is afraid to touch it.

Every change is a coin flip:

Dependencies aren't mapped. Downstream effects live in code nobody has read in years. Feature velocity collapses.

The last rewrite didn't work:

Leadership wants the real estimates, and you need a defensible reason to believe the next attempt will be different.

EltegraAI Platform Capabilities

Unlock legacy knowledge and cut your modernization from 18 months to 4.


Turn legacy code into a system your team can actually read

EltegraAI analyzes your legacy codebase and extracts business rules, data flows and hidden dependencies before any modernization work begins.

Your team starts modernization with understanding, not a guess.

EltegraAI Platform Interface 1

Replace tribal memory with a queryable system of record

Your Engineers ask EltegraAI any question about the system in natural language and get answers grounded in the actual code.

Institutional knowledge stops depending on the two engineers who are retiring.

Make AI coding agents finally work on legacy

EltegraAI feeds LLMs the architecture-aware context they need through MCP.

Hallucinations stop, and AI agents become useful for legacy modernization instead of being dangerous.

Walk into the budget meeting with evidence, not estimates

Our platform returns a defensible picture of what your system does and where the complexity lives - before you commit a timeline.

Modernization budgets get funded on proof instead of faith.

Other tools translate your code.
EltegraAI specifies your system.

What's inside the platform:

  • AI-powered parsing across COBOL, PowerBuilder, SQL stored procedures, Java, JSP, VB.NET, C#, Apex, Angular, React, HTML, JavaScript, Magic XPA, and more on request.

  • Reverse-engineers undocumented legacy systems into a queryable knowledge graph. No SME interviews. No Confluence archaeology. 

  • Turns decades of embedded business logic into human-readable BRDs, PRDs, user stories, and traceability maps your team can work from on day one.

  • Business requirements documents produced directly from your legacy codebase - fresh from the source, not from outdated specs or memory.

  • Ask our AI Chatbot any question about how a rule works or where a data field flows, and get an answer grounded in the actual code.

  • Connect EltegraAI to Claude, Cursor, GitHub Copilot, or any MCP-compatible AI agent - so your LLM gets the architecture-aware context it needs to generate code that matches the source system's behavior.

A glimpse of our client testimonials

"We'd been afraid to touch our core loan servicing platform for a decade. EltegraAI surfaced every business rule and dependency in the first 2 weeks. And our modernization roadmap finally has evidence."

- Chief Technology Officer, Regional Bank

Company size: 900+ employees
Modernized stack: COBOL → Java Spring Boot

“EltegraAI gave us a complete specification before we wrote a single line of new code. We now ramped-up in weeks instead of months, and the modernization program has a contract to build against."

- VP of Engineering, Property & Casualty Insurance

Company size: 1,500 employees 
Modernized stack: PowerBuilder → .NET Core

“Our original timeline to migrate 3M lines of codes was 18 months using Claude & internal team. With EltegraAI feeding context to AI coding agents, we compressed it to just over 3-4 months."

- Principal Engineer, Payment Processing 

Company size: 3,000+ employees
Modernized stack: SQL stored procedures → C# / .NET Core

Legacy in. Modern stack out. Behavior preserved.

EltegraAI can help you transform every core enterprise layer - applications, data, and infrastructure - with additional support available as needed.

Two ways of modernization with EltegraAI

  1. Run it independently with full platform access.

  2. Let our engineering team deliver the full modernization.

Questions we get before the first demo

  • AI coding agents reason from syntax. They hallucinate when business logic isn't documented. EltegraAI extracts the logic first and feeds it to your AI agent through MCP — so legacy conversion stops being a guessing game.

  • COBOL, PowerBuilder, SQL stored procedures, PL/SQL, Java, JSP, VB.NET, C#, Apex, Angular, React, HTML, JavaScript, Magic XPA. Stack not listed? Ask. We've added languages on customer request before.

  • Both. Run the platform with your engineering team, or have ours deliver end-to-end. Most teams pick a path during the discovery call after the code assessment.

  • The knowledge graph stays connected to your codebase. When engineering ships a change, the affected requirements, dependencies, and traceability update automatically.

  • A codebase assessment completes inside 2-5 business days. For live engagements, you have a working knowledge graph, structured requirements, and Jira-ready stories within the first week.

  • You get an export-ready pack: documentation, dependency maps, complexity heatmap, and a modernization timeline with estimates. Decide platform access, full delivery, or neither. No obligation.
