Recover the knowledge
Map existing behavior, dependencies, data flows, and undocumented business rules with the people who operate the system.
Application modernization
Plan the change. Preserve the business knowledge.
Understand an existing application, uncover its dependencies, and design a staged modernization plan. Guide your team through the decisions that shape a safe transition.
Architecture advisory
Built around a specific need.
Existing applications contain business knowledge that may be missing from documentation. We help you map that knowledge and compare migration options. Advisory reviews support your engineering owner through staged changes; any implementation work is agreed as a separate, bounded scope.
Discuss application modernizationWHAT THIS SERVICE COVERS
Choose the right boundaries
Identify which components to retain, wrap, refactor, or replace. Sequence migration around business continuity.
Verify the transition
Compare old and new behavior with representative scenarios, staged cutovers, and explicit rollback criteria.
ENGAGEMENT OUTPUTS
Something concrete
to build on.
↗Dependency and business-rule inventory
↗Target architecture and staged migration plan
↗Compatibility-test strategy and cutover guidance
The scope and deliverables are agreed for your engagement.
HOW RESPONSIBILITY WORKS
We own the assessment and migration design agreed with you. Your delivery team owns the migration programme and cutover approvals.
Compare engagement options ↗A PRACTICAL START
Preserve the behavior. Improve the foundation.
Begin with a critical workflow or a tightly bounded component whose behavior can be validated.
Map the current system
Review code, interfaces, data, and operational knowledge. Record critical business rules and the evidence behind them.
Design a migration slice
Choose a contained boundary with testable behavior. Agree compatibility requirements, data migration, and a way to reverse the cutover.
Validate in stages
Compare outputs with representative data, investigate differences, and release incrementally with monitoring and owner sign-off.
ILLUSTRATIVE ENGAGEMENT / NOT A CUSTOMER CASE STUDY
What this can look like in practice.
A business-critical application needs to change, yet its behavior is only partly documented. We help map dependencies and rules, then identify a migration slice that can be tested without committing immediately to a full replacement.
BEFORE WE START
What to bring.
- Existing code, system documentation, and interface inventory
- Domain experts who understand critical behavior
- Business-continuity requirements and known pain points
HOW WE ASSESS PROGRESS
What useful progress looks like.
- Important business rules are documented and validated
- Old and new behavior can be compared
- Each migration stage has acceptance and rollback criteria
BEFORE WE BEGIN
Your questions,
answered.
Do we need a complete rewrite?
No. An assessment may recommend retaining parts of the system, adding interfaces, or replacing a limited component. The choice depends on risk, cost, and the business need.
How do you handle undocumented rules?
We combine code and data analysis with domain-expert review. Inferred rules are treated as hypotheses until verified against representative scenarios.
