Old systems still run core parts of many businesses, but they are hard to change, hard to staff and closed to AI. We use Claude Code to read and document legacy code, migrate it to a modern stack on Azure or AWS, and add APIs and MCP servers so your teams and AI assistants can use your data safely.

The outcomes this service brings to your business.
A proven methodology to deliver exceptional results
We map the application, its data, users and integrations, and recommend whether to wrap it with an API, migrate it step by step or rebuild it.
Claude Code helps us extract business rules from the code, and your experts confirm them.
We move one module at a time and run old and new side by side where needed.
Every milestone ends with a QA test run that compares results with the old system.
We move users to the new system, retire the old one and support what we delivered.
Reading old code is the slowest part of most migrations. AI coding tools now do much of that reading: they summarize what each part of the code does and draft documentation and tests. Our engineers review every output. You get a clear picture of the old system before any code is rewritten.
A modern system is also the foundation for AI. AI agents need clean data and safe access to your systems. When we modernize, we add APIs and MCP servers, so you can add AI agents later without another rebuild.
We modernize with Claude Code, Anthropic's AI coding tool. ZetaBox is a Certified partner in the Claude Partner Network, and ten people on our team hold Claude certifications from Anthropic.
Legacy code read, summarized and documented, with engineers checking every result.
Controlled access for AI assistants to your modernized systems.
Work led by people who hold Claude certifications from Anthropic.

Spreadsheets, disconnected tools and legacy systems replaced with unified platforms.
It is the work of moving an old application to current technology so it is easier to maintain, secure and connect to other systems. Depending on the application, that can mean adding an API around it, migrating it module by module, or rebuilding it.
It depends on the state of the code, how well the business rules are understood and how much the application needs to change. The system assessment compares the options and recommends one, with milestones.
Yes. We start by documenting what the VB6 application does, then migrate it to .NET or a web application, one module at a time. Results are compared with the old system at every milestone.
No. We plan the migration in stages and run old and new systems side by side where needed. Users move to the new system only after it passes a QA test run.
MCP (Model Context Protocol) is an open standard that lets AI assistants such as Claude use business software. An MCP server sits in front of your system and decides which data and actions the AI can reach. It lets you add AI without giving it unrestricted access.
Start with a system assessment: a map of your application, a recommended path and a milestone plan.
