Every consulting firm wants to sell you a mainframe migration. But for most enterprises, the smarter move is renegotiating your mainframe terms. This paper challenges the migration-first narrative, provides a risk-adjusted TCO model, and delivers a negotiation strategy that secures 25–40% MLC and IPLA reductions.
Migration myth challenged, MLC & IPLA decoded, true TCO model (mainframe vs migration), 6 migration risks, 8 negotiation tactics, and 6 technical optimisation levers.
This is not a migration sales pitch. It’s an independent cost analysis that gives CIOs, CTOs, and infrastructure leaders the TCO comparison, risk assessment, and negotiation strategy needed to make the mainframe decision based on data — not consulting firm revenue targets.
Who benefits from migration (hint: not you). The 70% overrun rate. When migration genuinely makes sense vs when negotiation delivers better outcomes. The question nobody asks.
MLC pricing models (WLC, EWLC, TFP), the R4HA trap, IPLA one-time charges + S&S, and ISV tool costs. How each component works and where the savings are.
Side-by-side cost comparison including migration project fees, dual-run costs, risk contingency, retraining, and application risk. Why the negotiated mainframe is cheaper for 5–10 years.
COBOL conversion, batch replication, transaction integrity, talent/knowledge loss, testing coverage gaps, and vendor lock-in replacement. Each systematically underestimated by migration vendors.
TFP evaluation, R4HA optimisation, LPAR consolidation, IPLA caps, ISV rationalisation, migration-as-leverage, hardware refresh terms, and multi-year locks. Plus zIIP offload, WLM, Db2 tuning.
100% independent. No IBM, SI, or migration vendor partnership. Based on 50+ mainframe cost engagements. We have no incentive to recommend migration or retention — only what’s right for you.
Organisations that negotiate mainframe costs before evaluating migration achieve 25–40% MLC and IPLA reduction within 3–6 months. The savings change the migration business case fundamentally — and in most cases eliminate the financial justification for wholesale migration.
