Understand your legacy system before you try to replace it.
Most legacy modernizations fail because nobody fully understands what the old system actually does. We reverse-engineer your legacy system's business logic, data flows, and integrations — creating documentation that probably never existed.
Nobody Fully Understands the System You're Trying to Replace
- →Original developers are retired or gone — institutional knowledge walked out the door
- →Documentation is outdated, incomplete, or never existed in the first place
- →Business logic buried in thousands of lines of RPG, COBOL, or custom code with no comments
- →Hidden integrations and file transfers that nobody remembers until they break during migration
System Assessment & Documentation
Business Logic Extraction
Reverse-engineer business rules from running code — pricing logic, order workflows, allocation rules, and approval chains. Document what the system actually does, not what someone thinks it does.
Data Model Documentation
Map every table, field, relationship, and data flow. Identify master data, transactional data, and the transformations between them.
Integration Mapping
Discover and document every integration — file transfers, API calls, database links, email triggers, and manual handoffs. Nothing gets missed during migration.
Dependency Analysis
Identify upstream and downstream dependencies — which systems feed data in, which systems consume data out, and what breaks if something changes.
Technical Debt Inventory
Catalog customizations, workarounds, dead code, and technical debt. Distinguish between logic that must be preserved and logic that can be retired.
Knowledge Base Delivery
Deliver a structured, searchable knowledge base — not a 500-page PDF. Living documentation that your team and vendors can reference throughout the modernization.
The Engagement Process
Stakeholder Interviews
Interview power users, IT staff, and business process owners. Capture tribal knowledge before it disappears.
Code Analysis
Analyze source code, database schemas, and configuration files. Automated tools plus manual review for complex business logic.
Data Flow Tracing
Trace data from entry point through every transformation to output. Map the complete lifecycle of critical business objects (orders, inventory, customers).
Integration Discovery
Scan for file transfers, scheduled jobs, API calls, and database connections. Verify each integration with source and target system owners.
Documentation Delivery
Compile findings into a structured knowledge base with business process maps, data dictionaries, integration catalogs, and risk assessments.

Legacy Modernization · Assessment
Every engagement starts with an assessment.
We scope work after we understand your operation — not before. The Launchpad assessment maps where you are, quantifies what it's costing you, and sequences what to do first.
