01
The operating problem
Start with what must change.
A rewrite can repeat old mistakes at higher cost. Modernization starts by locating the constraints that make change unsafe or slow.
02
What this means in practice
A concrete working scope.
- Architecture and dependency assessment
- Target-state roadmap
- Incremental extraction or replacement
- Data and release transition plan
03
Engineering considerations
The details that matter.
- Modernize versus rebuild evidence
- Parallel-run and rollback strategy
- Business continuity
Frequently asked questions
Direct answers before the work starts.
$ 01Do we need a full rewrite?
Usually not. We prefer the smallest sequence of changes that materially improves safety and change speed.
$ 02Can modernization happen while the system stays live?
Often yes, with staged boundaries, compatibility work, and operational safeguards.
