The AS/400 is still powering global supply chains in 2026. Most people have no idea.

There are more than 100,000 AS/400 systems - officially IBM i now - still running actively worldwide.

Airlines. Banks. Manufacturers. Not as backup systems. As core operations.

IBM launched it in 1988. And it is, quietly, still one of the most reliable platforms in enterprise computing. People outside the industry find this hard to believe. People inside the industry find it completely unsurprising.

I spent years on green screens. Colleagues at Legacymigrations have walked into the server rooms of Austrian banks and manufacturing operations and seen them still there, still running, still doing exactly what they were put there to do.

That's not a problem. Reliability is a feature.

The issue is when the modern world needs to talk to it - and it can't. When the ERP needs a REST endpoint. When the analytics dashboard needs to pull from it.

That's when the conversation changes. Not 'replace this.' 'How do we build a bridge?'

And that's a solvable problem. Often more quickly and cheaply than people expect.

We're not going to claim we can administer your IBM i today - that's your team's territory. But we can help you understand what a sensible path forward looks like.
