Legacy modernization
A route off the system nobody wants to touch, taken in increments rather than a rewrite.
DEFINITION
Definition
Legacy modernization replaces a constrained system in bounded increments by mapping dependencies, isolating change boundaries and moving one capability at a time without requiring a full rewrite.
THIS IS FOR YOU IF
- You can provide access to the current system.
- A named owner can supply a named business decision maker.
- Your team needs a migration sequence, one working replacement increment and a cutover runbook.
HONEST FIT
Not for you if
the only acceptable outcome is a single immediate replacement of the entire existing system.
WHAT WE BUILD
The work inside the scope
Inputs from you: Access to the current system, Representative production records, A named business decision maker and Existing architecture documentation. Work items: Dependency and risk map, Change boundary design, Increment sequencing, Compatibility interfaces and Cutover and rollback planning. Together they produce a migration sequence, one working replacement increment and a cutover runbook.
