Reverse Engineer Legacy Systems in Hours.
Migrating legacy OLTP, OLAP, and ETL systems without complete system understanding leads to costly rework, missed dependencies, and stalled modernization timelines. 3X Reverse Engineer automatically deconstructs complex legacy databases and ETL pipelines, generating enterprise-grade documentation that captures every table, dependency, and business rule.
Legacy systems shouldn't hold your migration hostage.
Every delayed migration traces back to the same root causes: undocumented systems, tribal knowledge, and manual discovery that takes months before real work begins. 3X Reverse Engineer eliminates them systematically.
Undocumented Legacy Systems
Decades of undocumented Teradata, Oracle, SQL Server, and mainframe systems with no schema documentation, no data dictionaries, and no clear starting point for cloud migration planning. Teams inherit complexity they cannot see.
Tribal Knowledge at Risk
Critical business logic, transformation rules, and data relationships exist only in the heads of engineers who built them. When these SMEs move on, retire, or get stretched across projects, institutional knowledge disappears permanently.
Months of Manual Discovery
Teams spending 3-6 months manually tracing schemas, stored procedures, ETL dependencies, and cross-system data flows before a single line of migration or conversion work can begin. Discovery becomes the bottleneck.
No Functional Documentation for Conversion
Without documented business logic, data lineage, and object-level functional specs, accurate code conversion and data migration is guesswork. Teams discover logic gaps in production, not during planning.
Hidden Compliance and Data Risk
Unknown PII exposure, undocumented data quality rules, and missing lineage trails creating GDPR, HIPAA, and SOX compliance risks during cloud adoption. Auditors ask questions teams cannot answer without full system understanding.
Inaccurate Effort and Cost Estimates
Without automated complexity scoring and complete dependency mapping, migration budgets and timelines are based on assumptions. Projects overrun because the true scope of legacy systems is only discovered mid-flight.
Deep analysis. Complete outputs. Zero manual effort.
Six intelligent analysis modules automatically produce enterprise-grade documentation that would take senior architects months to create manually. From schema analysis to compliance reporting, every output is structured, searchable, and ready for migration planning.
Deep System Analysis
Automated examination of schemas, stored procedures, functions, views, triggers, and ETL logic across OLTP, OLAP, and hybrid database systems. Captures every object, relationship, and embedded business rule across the entire legacy environment.
Executive Summary Generation
AI-generated executive overview with system complexity assessment, modernization readiness scoring, risk analysis, cost drivers, and strategic recommendations. Gives CDOs and program leaders a complete picture without waiting for weeks of manual discovery.
Functional Documentation
Automated business logic documentation covering data flows, transformation rules, business processes, and the functional purpose of every object. Preserves institutional knowledge that would otherwise be lost when SMEs transition or legacy systems are decommissioned.
Technical Specification Extraction
Complete ERD diagrams, dependency maps, data lineage visualizations, integration points, and architectural pattern documentation generated automatically. Provides the technical blueprint that architects and engineers need to plan accurate target-state design.
Object Complexity Scoring
Automated classification and risk scoring of every database object by structural complexity, dependency depth, and cross-system references. Identifies high-risk migration candidates, estimates conversion effort per object, and prioritizes sprint planning with data, not assumptions.
Data Quality & Governance
Automated PII detection, data quality profiling, compliance gap analysis, and audit-ready governance reports for GDPR, HIPAA, SOX, and industry-specific regulatory requirements. Surfaces compliance risks before cloud migration begins, not after.
See every connection. Miss nothing.
3X Reverse Engineer automatically maps the full dependency graph of your legacy system from source tables all the way to downstream consumers.
See exactly what you get.
Every analysis run produces six categories of documentation. Here's a live preview of what lands in your team's hands.

Migration-ready outputs. From day one.
Everything your team needs to plan, estimate, and execute a confident legacy-to-cloud migration, generated automatically. No months of manual discovery. No guesswork in budgets or timelines.
Hours, Not Months
Complete reverse engineering, functional documentation, and migration-ready reports for complex legacy systems with 10,000+ objects delivered in hours. Eliminates the 3-6 months of manual schema tracing, dependency mapping, and SME interviews that stall most enterprise migration programs before real work begins.
SME-Level Documentation Quality
Documentation quality matching senior database architects with 15+ years of domain expertise. Every output includes functional context, technical precision, business relevance, and cross-system relationships. Captures the institutional knowledge your team needs, whether your SMEs are available or not.
Migration-Ready Deliverables
Executive summaries, object complexity scores, effort estimates per conversion tier, ERD diagrams, data lineage maps, and full technical specifications. Everything needed for accurate migration planning, stakeholder approval, and vendor scoping, packaged in structured, shareable formats.
Built-In Compliance and Governance
Automated PII discovery across every table and column, data quality profiling, and compliance gap analysis with audit-ready reports for GDPR, HIPAA, SOX, and enterprise regulatory requirements. Surfaces data risk and governance gaps before cloud migration begins, not during post-go-live audits.
