About us
legacyintegrations.com is a small, senior team of enterprise-integration engineers. We connect and migrate the systems that institutions depend on and are afraid to change — and we deliver it under liability, with cutovers that keep production running.
The work, in one shape: tangled point-to-point estates, resolved into a clean hub.
Platforms we work with
These are the platforms we integrate and migrate every day. If your estate runs on them, we already know where the bodies are buried.

Who we are
No offshore handoff, no junior team learning on your migration, no account manager between you and the engineer. When you talk to us about a Banner-to-Workday cutover or a PeopleSoft transfer, you're talking to the person who will write the mapping and run the reconciliation.
We've spent years doing the specific, high-stakes work of moving real data between real systems without breaking anything. That's the whole company: the database and middleware layer that makes a transformation actually real, rather than a slide deck about one.
How & why this happens
Wire systems together directly and the connections don't grow with the number of systems — they grow with the number of pairs. Drag the slider and watch the difference between point-to-point and a canonical hub.
Our Migration Risk Calculator scores your specific systems, integration count, and documentation — and tells you where the risk actually sits before anything is touched.
The shape of the work
Different names, different systems — but the underlying patterns repeat. Here's how the data actually moves.
Every system maps onto one clean model in the middle — so a change on one side never ripples across the others.
Extract, map, and load with validation at each stage. The unglamorous core of moving data correctly.
Changes propagate the moment they happen, instead of a nightly batch that is always slightly out of date.
Records moved from an old system to a new one with history intact and a rollout that stays reversible.
How we operate
We're a distributed team working across UK, US, and APAC business hours, so there's meaningful overlap with almost any institution's day. Work happens in focused blocks — deep, scheduled working sessions punctuating heads-down build time — rather than a wall of standing meetings.
Our environment is a working engineer's: everything under version control, changes shipped through CI, deployments reversible by design. You get direct, written access to the person doing the work, and a clear record of every decision.
Tell us the two systems and what you're trying to achieve. We'll come back with the approach, the risks we'd expect, and a fixed-scope range.
