Capture the system knowledge before it leaves with the people who hold it.

We map RPG programs, DB2 for i files, jobs, screens, interfaces, and operator knowledge into a practical modernization sequence without pretending IBM i itself is the problem.

What the modernization map captures

Built from the system, its logs, and its operators

RPG programs & call chainsMapped to business capabilities
DB2 for i files & logicalsTraced to producers and consumers
Jobs, queues & transfersSequenced with timing and dependencies
Concentrated knowledgeScored by succession risk
Questions the readout answers

Which capabilities are one retirement away from being unmaintainable?

Where can an API seam expose data without changing RPG?

Which 5250 workflows are worth a modern interface?

What should stay on IBM i indefinitely?

The platform is rarely the whole problem.

Business rules, integrations, operator knowledge, support clocks, and unknown consumers determine the safest path. We map those constraints before recommending retention, integration, incremental replacement, or retirement.

01

Critical operating knowledge is concentrated in a few people

One or two people know how the nightly jobs interact, which files are safe to touch, and why a program was patched in 2009. When they retire, the knowledge leaves with them.

02

Batch and file dependencies are poorly documented

Batch jobs, file transfers, and data queues form dependencies nobody has drawn. A change in one job can break a downstream process hours later.

03

Replacement plans confuse platform age with business risk

IBM i is not the risk. Undocumented programs, single points of knowledge, and closed interfaces are. The map separates the two so investment goes to the right place.

A decision-ready modernization blueprint.

Every engagement ends with a traceable estate view, a prioritized sequence, and explicit uncertainties your team can resolve.

D-01

Program and file map

Calls, files, jobs, screens, queues, transfers, and external consumers connected.

D-02

Succession-risk view

Capabilities with concentrated knowledge and fragile operating procedures prioritized.

D-03

Modernization map

A sequence for retaining, exposing, improving, or replacing capabilities based on evidence.

Scope. Scan. Verify. Roadmap.

The exception path comes before the happy path. Recommendations stay reversible until the evidence supports commitment.

Week 1

Kickoff and scope

We show you our in-house analysis system, which scans code, repositories, and databases, and agree the estate, the people, and what you will receive.

Week 2

NDA, access, and the scan

NDA signed and read-only access granted. Our system runs: data lineage traced, workflows identified, dependencies and consumers mapped.

Week 3

Verify and weigh the options

Engineers verify the findings with your team. Retain, integrate, wrap, replace, or retire: practical paths compared with their tooling.

Week 4

Roadmap and readout

Architecture, workflows, recommendations, risks, and a timeline with durations, documented and walked through with your decision makers.

30day assessment

Thirty days of read-only discovery and working sessions with your team. You finish with evidence, options, and a roadmap, not a sales proposal.

Start a 30-day assessment Scope: Fixed · Access: Read-only · Output: Written findings you keep

A 30‑day modernization assessment. Six answers in writing.

A-01

Where your estate stands

Applications, code, data, jobs, interfaces, and the knowledge concentrated in a few people, documented from evidence.

A-02

What you can do about it

Retain, integrate, wrap, replace, or retire: options per capability with their trade-offs stated plainly.

A-03

Which tools will help

Where AI-assisted code analysis, test generation, and migration tooling speed the work up, and where they do not.

A-04

What to improve in the process

Release, testing, support, and ownership practices that decide whether a modernization sticks.

A-05

How to upgrade the legacy system

A target architecture and a reversible path to it, without betting operations on one cutover weekend.

A-06

How long it takes, and the roadmap

Phases, durations, dependencies, and decision points your board or steering group can approve.

Build a defensible path beyond IBM i / RPG.

Bring the estate, the deadline, and the uncertainty. We’ll explain what can be learned safely before a modernization program begins. We will tell you when not to modernize it, and the assessment says so in writing.
