The approach
Map dependencies and business risk first. Introduce seams with the strangler pattern, migrate one capability at a time and validate behaviour with contract tests. A modular monolith is often a better first step than a service network.
What you receive
- An agreed scope and measurable acceptance criteria.
- Source code, documentation and architecture decision records.
- A delivery plan, knowledge transfer and clear next steps.
The first step
A conversation about the problem, constraints and desired outcome. Scope and the working model are agreed before implementation.
