Banking & FinServ Core Modernization

Modernizing the core — COBOL, mainframe, payments — without an outage or a failed audit, slice by slice under FFIEC/OCC, GLBA, and NYDFS Part 500.

Contents
  1. 01 Modernizing Legacy Banking Systems 14 min read Core banking and FinServ still run on decades-old COBOL and mainframe — why a big-bang rewrite is indefensible, and how a regulated institution modernizes the core slice by slice.
  2. 02 Core Banking Replacement vs Progressive Modernization 13 min read Rip-and-replace the core onto a packaged platform, or modernize it progressively slice by slice? The honest trade-offs, and how a regulated institution tells which path fits.
  3. 03 COBOL in Banking: The Risk Clock 12 min read Most core banking still runs on COBOL, and the workforce that understands it is retiring on a schedule. Why the talent cliff is the real forcing function — and how to capture the knowledge before it leaves.
  4. 04 Banking Modernization & Regulatory Compliance 13 min read FFIEC, OCC, GLBA, and NYDFS Part 500 mandate outcomes — security, resilience, auditability — not modernization. How a legacy core becomes a compliance liability, and how to remediate it slice by slice.
  5. 05 Payments System Modernization 12 min read Real-time rails, ISO 20022, and 24/7 settlement expose a legacy payments core like nothing else. How to modernize payments — without dropping, duplicating, or delaying a single transaction.
  6. 06 Zero-Downtime Banking Migration 13 min read How a regulated institution moves the core onto modern infrastructure without an outage — the strangler facade, shadow running, parity gates, and rollback at every step.
  7. 07 Banking Modernization Cost & ROI 13 min read What core banking modernization costs, the total cost of ownership a legacy core hides, the cost of not acting, and how to make the investment predictable rather than open-ended.
  8. 08 Core Banking Modernization Vendors 12 min read How to evaluate core banking platforms and the partner who migrates you onto them — what to ask, what to discount, and how to tell a real migration method from a confident promise.
  9. 09 Banking Modernization Statistics 11 min read The sourced, dated numbers behind core banking modernization — the COBOL footprint, the retiring workforce, the maintenance burden, and the market — with an honest account of what each does and does not prove.
