Legacy Modernisation
Moved forward without stopping the business.
The systems that are hardest to replace are the ones that matter most, which is why they are still running. We modernize them in stages, with the old system serving users until the new one has proven it can.
Replacing the engine while the vehicle is moving.
A big bang rewrite is the most common way modernisation fails. We move in pieces, keep both systems working during the transition and make every step reversible.
Knowing what you actually have.
What the system does, what depends on it, what the data looks like and which parts are undocumented. Most organizations discover their own system during this phase.
Piece by piece, with a way back.
Functionality moves in slices, users move with it, and the old system stays available until the new one has earned the traffic.
The part that decides whether it works.
Cleaning, mapping, reconciliation and verification, with both systems compared record by record before anything is switched off.
Some legacy is not software.
We have replaced paper based processes in public institutions with tracked digital workflows, which is the same problem with worse documentation.
From the map to the switch, with a way back at every step.
Map
Including what nobody wrote down.
Prioritize
Valuable and safe moves first.
Run both
The old system keeps serving.
Verify data
Record by record, reconciled.
Switch
Users trained and supported.
Retire
Decommissioned on a date.
Tax appeals moved from paper files to one tracked digital process, without stopping the institution.
One team, seventeen capabilities
We design, build and run custom software: web platforms, mobile products, AI systems and cloud infrastructure.
Highlighted is where you are. The rest is on the same team.
