Replace only what needs to change.

Tell us what you need
Visual concept · not client workKeep existing data and processes while renewing the experience.

Assess the current system

Review build, dependencies, data, integrations, tests, release process and operational constraints.

Compare options

Keep, upgrade, refactor, isolate, API-enable, replatform or replace. Each option has a different migration and operational cost.

Preserve behavior before changing structure

Characterization tests protect the behavior your operation depends on. A stable API can isolate a legacy module.

Plan a controlled change

Data recovery, rollout and stopping conditions depend on the system. Newer technology alone is not a success criterion.
