Legacy Modernisation
Replaced piece by piece, without halting operations.
- Operations keep running throughout the replacement
- Each migrated part goes into use immediately, rather than waiting for everything
- Can be stopped midway without discarding what has already moved
- Old data moves too, instead of being stranded in a dead system
- Documentation written from scratch for the parts that never had any
Typical scope
Legacy modernisation
The old system is replaced piece by piece while still running, until the last part has moved.
- Operations never stop during the replacement
- Can be halted midway without discarding what has moved
- Old data moves too, rather than being stranded
Typical duration: 3–12 months
Technical audit of a running system
A full read of a running system: code quality, unmaintained dependencies, security gaps, running costs, and which parts are genuinely dangerous to touch.
- A system map a non-technical person can read
- Which parts are dangerous to touch, and why
- Dependencies that are unmaintained or vulnerable
Typical duration: 2–3 weeks
Incremental legacy modernisation
Moving a legacy system piece by piece while the old one keeps running — rather than rewriting everything and hoping the switchover survives one weekend.
- The old system keeps running throughout
- Each stage delivers value on its own, not at the end
- A rollback path at every stage
Typical duration: 4–12 months, in stages
