Measure twice, migrate once.
Datawise assesses, migrates and upgrades the systems organisations depend on, especially the ones nobody fully understands anymore.
Systems rarely become black boxes overnight. The original designer moves on, a workaround becomes permanent, a new source is bolted on beside the architecture instead of inside it, and the documentation keeps describing a version that stopped running years ago. Nobody notices, because the system keeps working.
Until it has to change. Then the gap between what everyone believes the system does and what it actually does becomes the biggest risk in the project. That gap is where we work.
Legacy system assessment
Find out what a system really does before anyone changes it.
- What does this system actually do, and what depends on it?
- Is our data ready to move to the new system?
- Why doesn’t this number add up, and why is this so slow?
Data migration & upgrades
Move it, upgrade it or retire it, without losing anything on the way.
- A new system replacing an old one.
- A platform going out of support.
- A business acquired, carved out or merged.
- A system that can finally be switched off.
How engagements work
Most engagements start small: a few weeks’ work with a defined result. Understanding usually comes first, and it often leads to the move.
We take on a limited number of engagements at a time. Whoever scopes the work does the work.
Where we have done this
- An airline’s crew management system migrated without disrupting a single flight.
- A 24/7 toll tunnel migrated to a new transaction system with zero downtime.
- A bank’s market-data distribution system upgraded with no source code available.
- Six legacy systems of a utility and telecom company brought onto one platform.
- Two acquired businesses brought into a global SAP environment, their homegrown systems reverse-engineered along the way.
