Infor M3 (Movex)
End to end M3 and Movex support on IBM i: production support, integrations, and modernisation for manufacturing, distribution, and logistics operations.
Legacy
IBM i & AS400 Legacy Platform Modernisation
The generation that built your IBM i systems is retiring, and reliable RPG expertise is getting harder to find every year. We stabilise, support, and modernise the ERPs your operations depend on.
Overview
Thousands of Australian businesses run finance, inventory, manufacturing, and distribution on IBM i, and the platform is not the problem. The problem is that the generation of engineers who built those systems is retiring, and every departure takes irreplaceable knowledge of your RPG code, your DB2 schema, and the undocumented decisions holding it all together. Lexylon exists for exactly this moment: we read 30-year-old fixed-format RPG for a living, and we retire your key-person risk before it becomes an outage.
We bring deep, hands-on expertise across the ERP platforms Australian supply chains actually run: Infor M3 (Movex), Infor LX (BPCS), Infor System21, and bespoke RPG applications. That covers day-to-day production support, integration work, and measured modernisation, always without a predetermined migration agenda. If your stable RPG business logic is still earning its keep, we build around it rather than rewriting it.
The engagement covers every step of the journey: before, during, and after transformation. Ongoing RPG, DB2, ERP, production and integration support with 24/7 options, delivered by Melbourne and Sydney on-site teams with Australian and European delivery capability. Your operations get stability first, modernisation second, and a partner who stays.
ERP platforms
Deep expertise across leading IBM i ERP platforms
Infor LX (BPCS)
Specialist Infor LX and BPCS expertise across implementations, upgrades, RPG customisations, and integration with modern web, mobile, and cloud platforms.
Infor System21
Extensive System21 experience on IBM i: application support, Aurora upgrades, RPG enhancements, and integration across finance, supply chain, and warehouse modules.
Bespoke RPG & DB2 Systems
Support and modernisation for in-house RPG applications: code archaeology, documentation, DB2 database engineering, and safe enhancement of undocumented legacy systems.
The proof
Architecture & tech stack
RPG programs as REST and SOAP APIs
Plenty of stable RPG logic has decades of business rules baked in. We keep your existing IBM Integrated Web Services endpoints running and publish the same programs as secure REST or SOAP services, so nothing that works gets rewritten for the sake of it.
DB2 for i data services and stored procedures
Fast, controlled access to your IBM i data through SQL services and stored procedures. Reporting tools, web portals, and integrations read what they need while DB2 stays the single source of truth.
SOAP to REST modernisation, backed by real business logic
Older SOAP integrations get transformed into clean, documented REST APIs with OpenAPI contracts. The proven RPG processing behind them keeps doing the work; only the interface changes.
Integration middleware built for IBM i
A secure layer that connects your IBM i to web, mobile, cloud, eCommerce, and AI platforms. It can run on the IBM i itself, authenticated with native user profiles and certificates through the Digital Certificate Manager, or sit beside it in the cloud.
24/7 IBM i production and integration support
RPG, DB2, ERP, and integration support with round-the-clock options and defined response times. We stay engaged before, during, and after modernisation, which is usually when it matters most.
AI on IBM i
Bring AI to the system that runs your business
AI has just become a top five priority for IBM i teams worldwide, and the number one concern is finding the skills to act on it. Here is the part that gets missed: your DB2 database already holds decades of clean, structured operational history, which is exactly what AI models need. We bring the AI practice and the IBM i depth in one team, so intelligence lands on your data without risking the core or shipping it offshore.
Anomaly detection on live operations
Transactions and telemetry from your ERP, watched continuously for the patterns that precede failures, stock-outs, and fraud. Alerts arrive before the 2am phone call does.
Demand forecasting from your own history
Decades of orders, seasons, and exceptions in DB2 become forward looking forecast reports your planners can actually act on, delivered into the tools they already use.
Private AI copilots over ERP data
Ask questions of your business in plain language and get answers grounded in live DB2 records. It runs inside your security boundary, on premise or in your tenancy, and every answer cites its source.
Execution methodology
01
Stabilise
We audit the estate, read the RPG source, and put immediate support cover in place. Key-person risk is retired first, so the business is protected before anything changes.
02
Modernise incrementally
Existing IWS and SOAP services keep running while REST middleware lands beside them, hosted on the IBM i itself or on Terraform-managed cloud infrastructure, whichever suits your environment. Every cutover is parallel run, measured, and reversible, with zero downtime.
03
Support for the long term
24/7 monitoring and defined response targets from Melbourne and Sydney on-site teams, with Australian and European delivery capability behind them.

FAQ
IBM i questions we hear most
Who supports Infor System21 in Australia?
Lexylon provides specialist System21 support, integration, and modernisation from Melbourne and Sydney, backed by Australian and European delivery capability. We cover production support, RPG and DB2 work, and 24/7 options for business-critical environments.
Can you support our AS400 if our RPG developer retires?
Yes. Eliminating key-person risk is the most common reason clients engage us. We read and document your existing RPG source, take over production and integration support, and keep your ERP stable while you decide what happens next.
Do we have to migrate off the AS400 to get modern web and mobile apps?
No. We expose your existing RPG business logic through secure REST and SOAP services, so modern web and mobile applications run against the same trusted DB2 data. The core keeps running, and nothing is rewritten unnecessarily.
Can you modernise our existing IBM i SOAP web services to REST?
Yes. We maintain your current IBM Integrated Web Services SOAP endpoints while transforming them into documented REST APIs with OpenAPI contracts, retaining the proven RPG processing behind them where it provides value.
Do you provide 24/7 support for IBM i production systems?
Yes. We offer ongoing RPG, DB2, ERP, production and integration support with 24/7 options and defined response targets, before, during, and after any modernisation work.
Can we add AI to our AS400 without replacing it?
Yes. Your DB2 data already holds the history AI needs. We connect anomaly detection, forecasting, and private AI copilots through the same secure middleware we use for integration, so the core system is never modified and never at risk.
Does using AI mean sending our IBM i data to the cloud?
No. We build sovereign AI architectures that run on premise or in your own tenancy. Retrieval and generation happen inside your security boundary, and your data never leaves your control.
How much does the initial consultation cost?
Nothing. The first discovery session is free of charge. We analyse your environment and the problem you are trying to solve, then come back with a proposed solution and costed options. You decide whether to proceed.
Engagement models
Three ways to engage, one transparent cost structure
IBM i support runs naturally as a dedicated retainer, while modernisation modules are usually priced as fixed packages of effort.
Dedicated team
A stable squad of Lexylon engineers reserved for your roadmap, month after month. Predictable capacity, a predictable invoice, and a team that compounds knowledge of your business.
Time and materials
Pay only for the hours worked, at some of the most competitive rates in the Australian market. Ideal when scope moves, with timesheets you can read and question line by line.
Project or module based
A fixed price built up from an honest effort estimate in hours, module by module. You see exactly how the number was reached before you sign, and it does not move unless the scope does.
