Legacy application modernisation
Modernise old systems without stopping the business.
Assess, refactor or replace legacy applications in safe stages, each one usable and reversible.
Why teams call us
Problems this solves
-
01
Unsupported technology
Old PHP, .NET or Java versions no longer receive security updates.
-
02
Knowledge leaving with people
Only one or two people understand how the system works.
-
03
Changes take months
Every change risks breaking something else.
-
04
A full rewrite feels too risky
Big-bang rewrites are expensive and often fail.
Our approach
Most modernisation fails when it is attempted all at once. We start with an assessment of the code, data, integrations and risks, then modernise in stages: upgrading runtimes, adding tests around critical behaviour, extracting or replacing parts one at a time, and moving to modern hosting.
Each stage delivers something usable and has a rollback plan, so the business keeps running throughout.
