A sample console with made-up data.

Writing the new code is the easy part Finding everything, reading it, and proving nothing changed take the time

Nobody wrote the rules down

Decades of business rules live inside RPG and Synon code, and the people who knew them have moved on.

Some programs never show up

Programs called from messages or menus are invisible to a scan, so a plan built on one leaves them behind.

A screen can look right and be wrong

A converted program can show the same screen and still write the database differently.

One call stream goes from green screen to Azure Agents do each step, and a person signs off before the next

Inventory agent

Every program, including the ones a scan misses

It follows every call, menu, and message, so a program that only runs from a message still makes the plan.

Your experts confirm the inventory before anything moves.

Call stream agent

Call streams you can move one at a time

Programs that run together are grouped, and shared programs are tested in every stream that uses them.

You choose which stream moves first.

Code agents

Rules written down, then rewritten

Each rule comes out in plain language, and the new code carries the rule's name, so anyone can trace it back.

Every change is a pull request an engineer reviews and signs.

Test agent

The same transaction, compared field by field

Every transaction runs on the green screen and the new app, and the database writes are compared.

A single mismatch stops the release.

Live on Azure, in your own tenant

Each call stream ships to standard Azure services, with sign-in by role, open APIs, and monitoring from day one.

The old program retires only when its stream is live.
