ConchoFull-codebase intelligence
Business rules, architecture layers, and integration points indexed across your entire codebase before planning begins.
The problem
You can't modernize what you don't understand.
70% of large-scale modernizations fail — not because of bad technology, but because nobody fully understood the existing system first. LLMs alone can analyze only about 30% of a large codebase before hitting context limits. The rest gets guessed at. Concho analyzes 100%.

What Concho adds
Affinity-driven migration
Not everything transcodes 1:1 — and you probably don't want it to. Concho preserves business rules while eliminating legacy constraints.
Built-in validation
Every claim about your legacy system is checked against the source before it enters the plan. No fabricated file references. No invented rules.
How it works
Six steps from analysis to deployment.
01 · Analyze
Map current architecture, business rules, data schemas, integrations, and code-to-data mapping across the full system.
02 · Plan
Select target subsystems, extract rules, define affinity boundaries, design service architecture, and map the cutover strategy.
03 · Validate
Every assumption is automatically checked against the source system. No hallucinations make it into the plan.
04 · Review
Guide architecture decisions, make course corrections, and iterate until the plan is exactly right.
05 · Generate
Produce containerized services, database schemas, deployment scripts, and modern UI — all governed by validated affinity rules.
06 · Ship
Stakeholders receive a comprehensive report covering analysis, the plan, and generated artifacts. Review, approve, deploy.
Sample deliverables

Concho produces an executive summary and a full stakeholder review for every engagement. Read the COBOL and .NET examples below — the actual deliverables, published in full.
48-year-old COBOL ERP
ACAS Payment Processing
Legacy payment processing with deeply embedded business rules and decades of architectural sprawl, analyzed end-to-end with a complete modernization blueprint.
The legacy system limited payment processing to 9 invoices at a time. Concho identified the root cause and designed the path to eliminate it.
Enterprise-scale .NET platform
Petra Gift Processing
Interconnected systems, layered architecture, and operational dependencies — analyzed end-to-end with a structured migration strategy.
Enterprise-scale modernization intelligence across the full application landscape.
