Legacy Modernisation
Neural Inverse includes a structured 5-stage migration platform for modernising legacy codebases. It pairs one or more source (legacy) projects with one or more target (modern) projects, walks you through each stage with AI assistance and compliance enforcement, and produces a tamper-evident audit bundle at cutover.
Legacy modernisation is available in the open source edition.
The 5 Stages
| Stage | Name | What Happens |
|---|---|---|
| 1 | Discovery | Scans source project — languages, dependencies, compliance patterns, tech debt |
| 2 | Planning | Generates CPM-scheduled migration roadmap with effort estimates and blocker detection |
| 3 | Migration | Unit-by-unit AI translation with fingerprint comparison and approval gating |
| 4 | Validation | Equivalence testing, divergence analysis, compliance sign-off |
| 5 | Cutover | 8-point readiness gate, file commit, audit bundle export |
Supported Migration Domains
- Mainframe & Legacy: COBOL, FORTRAN, PL/I, RPG (AS/400), Natural (Adabas), MUMPS, Ada, PowerBuilder
- Firmware & Embedded: Bare-metal C/C++, ARM/AVR Assembly, RTOS migration (FreeRTOS, Zephyr)
- Industrial & OT: IEC 61131-3 (Ladder Logic, Structured Text), PLC-to-IPC, SCADA, OPC-UA, Modbus
- Automotive: AUTOSAR Classic-to-Adaptive, ISO 26262 ASIL uplift, CAN DBC migration
- Telecom & 5G: O-RAN, 3GPP NF migration, TTCN-3-to-pytest, SS7/SIGTRAN
- Database: Oracle-to-PostgreSQL, stored procedure extraction, DB2, Sybase
- Framework: Angular.js-to-Angular, .NET Framework-to-Core, Java EE-to-Jakarta
60+ migration pattern presets covering all major legacy modernisation use cases.
How Sessions Work
A modernisation session connects projects via a Modernisation.inverse file written to each project root. This file records the session ID, migration pattern, role (source or target), and paired projects. It is written by the IDE — not generated by AI — so it survives IDE restarts and can be committed to version control.
Sessions support four topologies: 1:1, 1:N, N:1, and N:M.
Opening the Modernisation panel from within any project that contains a Modernisation.inverse file automatically restores the session.
Quick Start
Cmd+Alt+M Open Modernisation panel- Click New Modernisation Project
- Select a migration pattern
- Pick source and target folders
- Run Discovery → approve the Plan → migrate unit-by-unit → validate → cut over
See Getting Started for a step-by-step walkthrough.
