Legacy Migration Tool

Modernise legacy systems with less risk and less rework

APTO helps teams assess legacy applications, map business logic, modernise core workflows, and generate migration-ready outputs for target platforms — with validation steps built in for a more controlled transition.

What the Migration Tool handles

Legacy Code Assessment

Reviews legacy applications, identifies core business rules, and maps dependencies across modules, workflows, and supporting systems.

Architecture Planning

Helps translate older application structures into modern, modular architectures aligned to your target platform and delivery goals.

Data Migration Readiness

Maps schemas, data relationships, and migration logic to support a cleaner move from legacy data stores to modern database platforms.

API & Integration Modernisation

Reworks older integrations into cleaner service layers and API-ready interfaces that are easier to maintain and extend.

Validation & Test Support

Supports regression validation and behavior checks so teams can compare expected outcomes before moving into production.

Cutover Planning

Enables phased rollout and transition planning so teams can move with more control instead of relying on a risky all-at-once switch.

Migration process — 5 guided phases

1
Scan & Assess

Review the legacy application, dependencies, and critical business flows

2
Map & Plan

Define the target architecture, migration scope, and transition approach

3
Generate & Prepare

Produce migration-ready outputs for the selected modern stack

4
Validate & Compare

Check business behavior, outputs, and data handling before release

5
Roll Out & Transition

Move in stages with review points, monitoring, and rollback planning

Everything to build & run production software

A unified AI platform — from first line of code to live production operation — built for speed, reliability, and scale.

AI Code Generator

Describe features in plain English. APTO writes standardised, deployable code across your entire stack — frontend, backend, and database.

Visual No-Code Builder

Drag-and-drop UI for designing screens, workflows, and business logic. Build production apps without writing a single line of code.

Engineering World Model

A living model of how your software actually works — grounded in code, tickets, observability data, and organisational decision history.

Built-in DevOps

CI/CD pipelines, one-click cloud or on-premise deployment, and automated testing — baked directly into the platform.

Roles & Permissions

Enterprise-grade access control with granular role management, SSO support, and audit trails for secure, compliant applications.

Institutional Memory

Resolved patterns, decisions, and validation history stay attached to the next workflow — not siloed in outdated Confluence pages.

Autonomous agents that understand your software

APTO's AI production agents autopilot SRE, support, and QA — using a living model of your codebase to maintain and operate complex production systems.

SRE Agent

Incident Response & Monitoring

Continuously monitors production, pinpoints root causes against your codebase model, and coordinates resolution — without manual triage.

98%Reduction in Mean Time to Recovery (MTTR)
Support Agent

Intelligent Ticket Triage

Routes tickets to the right team instantly by understanding your system's structure. Eliminates context loss between handoffs and departments.

15 minTriage time, down from 3 days
QA Agent

Parallel Regression Validation

Runs parallel simulations against expected behaviour before every release — surfacing regressions automatically before they reach customers.

A living model of how your software actually works

APTO's SIM-1 engine builds an Engineering World Model — a unified, continuously updated representation of your entire system grounded in real code and real decisions.

  • Coordinated delegation — agents split work by owner and track responses in a unified workflow, eliminating cross-team handoff friction.
  • Parallel simulations — scenario runs that surface regressions before a single line of code reaches production.
  • Institutional memory — resolved patterns and validation history stay attached, so every new workflow benefits from everything learned before.
  • Zero context loss — no more "who owns this?" or "why was this built?" — the model always knows.
