Legacy system review
and dependency mapping.

We inventory components, data stores, integrations, deployment environments and owners, then deliver a current-state system map and dependency register.

OperationsRuntime and ownership
Conceptual technical decision room with architecture sheets, decision records and a wall-mounted dependency map.

We build the map from technical records and owner input.

We review repositories and build files, database schemas and data flows, interface specifications and schedules, environment configuration, release and incident records, and the people responsible for operating the platform.

The result shows what runs, what changes together, who owns each dependency and which missing facts need a test or a named decision before migration begins.

Sources and system areas included in the review.

The exact depth follows the agreed scope. Each source is tied to a component, dependency, owner or migration constraint.

Components

Repositories, builds and jobs

Applications, services, libraries, scheduled jobs and deployment units show what executes and changes together.

Data

Schemas, stores and flows

Ownership, transformations, retention, read and write paths show what must remain consistent during a move.

Integrations

Interfaces and schedules

API specifications, file transfers, protocols, schedules, credential ownership and failure behavior show external dependencies.

Technology

Languages, frameworks and runtimes

Supported versions, libraries, database engines, hosting platforms and build tools show what can stay, what needs an upgrade and what creates a migration constraint.

Ownership

Operators and decision owners

Technical owners, operational owners and acceptance owners clarify who supplies evidence and approves each state.

Unknowns

Tests and missing records

Missing documents, conflicting records and assumptions are listed with the test or responsible owner needed to resolve them.

You receive three review outputs.

Current-state system map

Components, stores, interfaces, environments and owners inside the agreed platform boundary.

Dependency register

Each relationship, its source, owner, migration effect and any unresolved condition.

Modernization route options

What can stay, separate, become compatible or require replacement, with the reason for each option.

Tell us which platform area needs review and what must remain operational.
