"There are still 220 billion lines of COBOL running the world's banks, insurance companies, governments, and supply chains." — Reuters, 2024
Every enterprise modernizing legacy COBOL hits the same wall:
| Pain Point | Reality |
|---|---|
| 💰 Migration cost | $5M – $50M per program portfolio |
| ⏱️ Validation time | 6–18 months of manual line-by-line checking |
| 🐛 Defect leakage | 1 in 4 modernized programs ships with output mismatches |
| 🚫 Project failure rate | 70% of mainframe migrations stall (Gartner) |
| 🧓 COBOL expertise | Vanishing — average COBOL engineer is 55+ |
Writing modern code isn't the bottleneck. Trusting it is.
Until output parity is mathematically proven, businesses can't cut over. Migration projects sit in "validation purgatory" — burning budget, blocking innovation, risking outages.
MigrateIQ is a reasoning multi-agent AI system that automatically validates modernized code against the legacy COBOL source-of-truth — and proves byte-level output parity in minutes.
It is not a code converter. It is the trusted final checkpoint that unblocks every other modernization tool on the market.
| Traditional Approach | MigrateIQ Approach |
|---|---|
| 👨💻 Manual line-by-line review | 🤖 5 specialized AI agents collaborating |
| 📋 Spreadsheet diffs | ⚡ Byte-level automated comparison |
| ❓ Guess the root cause | 🧠 Reasoning grounded in COBOL source |
| 🔥 Hallucinated AI fixes | 📚 Foundry IQ cited retrieval |
| 🐢 6–18 months | ⏱️ Minutes per program |
| 💸 Millions in QA labor | 💚 Fully automated workflow |
Mainframe modernization is one of the largest IT challenges of this decade — affecting banking, government, healthcare, logistics, telecom, and utilities.
| Metric | Before MigrateIQ | With MigrateIQ |
|---|---|---|
| 👥 QA engineers per migration | 8–15 specialists | 1 reviewer |
| ⏱️ Validation cycle time | 6–18 months | Hours to days |
| 🎯 Defect detection accuracy | ~85% (sampling) | 100% (byte-level) |
| 💰 Validation cost | $2M – $8M | $50K – $200K |
| 🚀 Time to production | 18 months | 3 months |
| 🌱 Carbon footprint | Months of mainframe hours | Cloud-native cutover |
💡 MigrateIQ doesn't replace modernization tools — it unlocks them by removing the validation bottleneck that stops 70% of these projects from finishing.
MigrateIQ orchestrates 5 specialized AI agents through a deterministic 9-step pipeline. Every step is observable, replayable, and auditable — engineered for enterprise trust.

| Agent | Role | Reasoning Capability |
|---|---|---|
| 🔧 DevOps Agent | Pulls latest converted code from version control | Branch resolution, PR-aware |
| ⚙️ Script Runner | Builds & executes both modern and COBOL programs | Sandboxed execution, output capture |
| 🔍 Compare Agent | Performs byte-level output diff | Field-aware, format-aware comparison |

| 🧠 Analysis Agent | Reasons over failures, suggests grounded fixes | Foundry IQ grounded retrieval, multi-hop reasoning |
Foundry IQ is MigrateIQ's reasoning brain — and our defense against AI hallucination.
Without grounding, LLMs invent fixes that look plausible but don't match COBOL semantics. In enterprise migration, a hallucinated fix can introduce silent defects worth millions.
Foundry IQ eliminates that risk.

🛡️ Reliability & Safety MigrateIQ is engineered for enterprise-grade trust — because mainframe modernization is mission-critical.
| Concern | MigrateIQ Mitigation |
|---|---|
| 🎭 LLM hallucination | Foundry IQ grounded retrieval — every claim cited to source |
| 🔄 Non-determinism | Fixed 9-step workflow with idempotent stages |
| 🔥 Cascading failures | Per-step graceful fallbacks; failures isolated to agent boundary |
| 🔐 Secret leakage | All credentials via .env (never committed); .env.example template |
| 📜 Auditability | Every reasoning step logged with inputs, outputs, citations |
| 🧪 Reproducibility | Sessions persisted; replayable end-to-end |
| 🎯 Output verification | Byte-level diff is deterministic ground truth — no "AI says it's fine" |
| 🌐 Multi-LLM resilience | Auto-failover between primary and fallback LLM gateways |
| 🏢 Enterprise data safety | Code never leaves customer environment; on-prem deployable |
🧠 Why Reasoning ≠ Hallucination Here A common pitfall in agentic systems is "the agent decided it was correct." MigrateIQ avoids this by design:
Truth comes from execution, not the LLM. Both COBOL and modern programs run in real sandboxes, and outputs are diffed at byte level. The LLM only reasons about why outputs differ — it never decides whether they match. Every fix suggestion is grounded — Foundry IQ requires a source citation before the Analysis Agent can recommend a change. This separation of concerns is what makes MigrateIQ safe to use in regulated industries (banking, insurance, government).
