Unlocking Solvency II Confidence: How Data Lineage Transforms Legacy Systems from Liability to Asset

Something structural is shifting in consulting - and the firms paying attention are rethinking how they staff, price, and deliver client work as a result.

Clients are pushing back on people-heavy, time-and-materials engagements. They're asking harder questions about what they're actually paying for, and in some cases they're building internal capabilities rather than renewing multimillion-dollar consulting contracts. The era of charging by the hour for work that AI can now accelerate dramatically is under visible pressure - and the consulting industry is feeling it.

Nowhere is this tension more acute than in financial services technology delivery, where data migration sits at the center of nearly every major transformation program. It's the workstream that consumes the most analyst hours, carries the most project risk, and is most likely to determine whether a client engagement ends with confidence or – in the worst case – with a lawsuit.

The firms finding a path forward are the ones investing in AI-powered delivery capabilities - not as a marketing claim, but as a genuine operational shift that changes what they can promise and reliably deliver.

The Billing Model Under Pressure

The numbers behind the shift are striking. Business Insider reported in November 2025 that McKinsey disclosed roughly a quarter of its global fees now come from outcomes-based arrangements - a notable departure for an industry where traditional time-based billing has dominated for decades. EY's leadership has openly acknowledged the same pressure, with executives suggesting that AI could push consulting toward a "service-as-software" model where clients pay for results rather than labor. PwC, meanwhile, reduced its global headcount by more than 5,600 in 2025 - a signal that the people-heavy delivery model is already under structural strain.

The underlying tension is straightforward: AI makes consultants dramatically more productive, but most revenue models still depend on billable hours. A task that once required 60 hours can now be completed in 6. If firms deploy AI aggressively, they either earn less revenue for the same work or they have to fundamentally rethink how engagements are scoped and priced.

Buyer expectations are shifting - clients increasingly want to pay for results. The pressure is real and it's intensifying. Consulting firms that once relied on junior teams to churn through data-heavy work are now discovering that clients can replicate that output with an off-the-shelf AI tool and a couple of their own analysts - and they're asking why they should keep paying consulting rates for it.

When Delivery Fails, the Stakes Are High

The pressure on consulting firms isn't only coming from pricing conversations. It's coming from clients who are done absorbing the cost of programs that don't deliver.

In September 2025, Zimmer Biomet filed a $172 million lawsuit against Deloitte Consulting over a botched SAP S/4HANA implementation. The complaint alleged that Deloitte misrepresented its capabilities, assigned undertrained and constantly rotating offshore teams, and concealed system defects before a July 2024 go-live that left the company barely able to ship products, issue invoices, or generate basic sales reporting. The total damages sought included $94 million in fees paid to Deloitte, $15 million in additional remediation invoiced by Deloitte itself, and $72 million in Zimmer Biomet's own post-go-live costs.

The case is still working through the courts. But regardless of outcome, it illustrates a broader dynamic: clients are no longer absorbing failed technology programs quietly. They are quantifying the damage and pursuing accountability. And for the consulting firms delivering these programs, the risk profile of a poorly managed implementation has grown considerably.

In financial services -- where a data error doesn't just cause operational disruption but can trigger regulatory scrutiny, client relationship damage, and audit findings - the consequences of delivery failure are even more pronounced. A migration that goes wrong at a bank or asset manager isn't just a project problem. It's a systemic risk event.

Where Financial Services Delivery Is Uniquely Hard

Financial services technology programs put consulting teams in a particular bind. The work is genuinely complex, the data is dense, and the tolerance for error is narrow - yet the pressure to compress timelines and control costs is as high here as anywhere.

Consider what a typical data migration engagement looks like in this space. A bank modernizing its legacy infrastructure, an asset manager consolidating data after an acquisition, or an insurance carrier migrating off a legacy policy administration system - each arrives with decades of client data stored in formats that weren't designed for portability. Position histories across multiple asset classes. NAV records from prior administrators. Interest calculations embedded in COBOL modules that haven't been touched since the 1990s. Counterparty hierarchies full of historical exceptions and overrides.

The consulting team's job is to move all of that accurately, quickly, and in a way that satisfies both the client's operational requirements and the regulatory frameworks that govern their data. BCBS-239 for global systemically important banks. ORSA and Solvency II for insurers. The compliance dimension means that reconciliation isn't just a technical milestone - it's an evidence-gathering exercise that regulators will review.

And yet, this is precisely the work that has traditionally been done manually: analysts comparing schemas side by side, writing transformation rules by hand, iterating with target systems through slow feedback loops. It's time-intensive, expertise-dependent, and difficult to scale.

The Legacy System Problem No Standard Playbook Solves

A significant share of financial services programs involve migrating data off legacy systems - mainframes running COBOL, AS/400 environments running RPG, or custom platforms whose original developers retired years ago. For consulting teams, this creates a structural challenge that sits upstream of everything else: the source system is a black box.

The business logic governing how data is calculated, transformed, and stored in these systems was often never externally documented. It lives in the code - in tens of thousands of COBOL modules, in conditional branching logic written to solve a specific business problem and never touched again. When a consulting team needs to understand why a risk calculation produces a particular result, or how two legacy fields need to be combined before they can map to a target schema, they often have no reliable starting point.

The traditional answer has been to engage the institution's mainframe specialists - a small, typically overburdened group who are simultaneously managing live operations and fielding questions from the migration project. Analysis that should take days can take weeks. And when those specialists retire, the institutional knowledge goes with them.

Contextual data lineage changes this calculus entirely. AI-powered platforms can parse thousands of COBOL or RPG modules and surface the calculation logic, data flows, field relationships, and branching conditions embedded in legacy code - in minutes rather than months. For consulting teams, this means arriving at the analysis phase with a structured, searchable map of what the legacy system actually does, before a single record is moved.

That foundation changes everything that follows. Learn more about what contextual data lineage reveals in legacy financial systems.

How AI Changes the Delivery Economics and Predictability

For consulting firms navigating the shift toward outcomes-based pricing, AI-powered data migration tooling offers a concrete path to better margins and better delivery - simultaneously.

The efficiency gains are measurable and meaningful. Business analysts on AI-assisted migration projects work up to 6x faster. Migrations complete up to 80% faster overall. and the work that once required senior technical resources increasingly flows through analysts with the right platform behind them.

In a financial services context, these gains show up in specific, high-stakes ways:

• Early data profiling gives consulting teams a clear picture of source data quality - completeness rates by field, currency distributions, unique values, anomalies -- before execution is underway. For a senior project manager, this visibility is the difference between a defensible timeline and one that keeps slipping.
• Predictive field mapping eliminates the blank-spreadsheet start. AI-generated mapping predictions -- ranked by confidence, ready for review -- compress what is typically the most expertise-heavy step into a validation exercise. Business analysts can own the work end-to-end, without requiring a senior SME to perform what is fundamentally an analyst-level task.
• AI-assisted transformation handles the precision that financial data demands: standardizing identifiers, reformatting currency codes, reconciling accounting bases, applying calculation logic consistently across millions of records. Work that previously required a systems engineer can be completed by a business analyst -- which directly affects how engagements are staffed and priced.
• A single, governed platform replaces the sprawl of spreadsheets, email threads, and siloed tools that typically fragment a migration engagement. Every mapping decision, transformation rule, and data file lives in one place -- visible to every teammate, maintained in a consistent state, and managed through a structured workflow rather than tribal knowledge. For consulting firms, this is what makes delivery governable at scale: the engagement doesn't live in an analyst's head, it lives in the platform.

For consulting firms, the deeper advantage is structural. Zengines is the single source of migration truth -- where every decision is made, every rule is stored, and every teammate works from the same live picture. Profiling feeds mapping. Mapping feeds transformation. Transformation feeds testing. The engagement lives in the platform, not in any one person -- which means it's scalable, transferable, and consistently deliverable regardless of who is staffed on the next one.

From Effort to Outcomes: Making the Transition Real

The shift to outcomes-based delivery isn't just a pricing conversation - it's an operational one. Firms can't credibly commit to delivery outcomes on fixed-fee or risk/reward structures if their underlying methods are still dependent on manual, labor-intensive processes that are inherently unpredictable.

This is the core reason why AI tooling matters so much for consulting firms right now. It's not about replacing consultants - it's about giving delivery teams the infrastructure to make commitments that they can keep. When field mapping is AI-assisted, reconciliation is automated, and data quality is profiled upfront, project timelines become far more predictable. And predictability is the prerequisite for outcomes-based pricing.

Firms building these capabilities are finding that they compete differently. They can take on fixed-fee engagements with genuine confidence rather than aggressive contingencies. They can staff programs leaner without sacrificing quality or pace. They can have more credible conversations with financial services clients who have been burned before and are scrutinizing methodology more carefully than they used to.

The Big 4 and major systems integrators are all investing in AI platforms - EY's AI Agentic Platform, Deloitte's Zora AI, KPMG's and PwC's respective investments - but rolling out new tooling across thousands of staff, multiple service lines, and global operations takes time.

The firms moving fastest are the ones being strategic about where AI solves the most acute delivery problems first. In financial services technology programs, that means data migration and legacy system analysis.

What This Means for How Firms Compete

Financial services clients have long memories when it comes to failed implementations. Many have lived through at least one program where data issues surfaced late, caused delays, and required expensive remediation. They ask harder questions in proposal stages now, and they're paying close attention to how prospective partners describe their methodology - not just their credentials.

Consulting firms that can demonstrate AI-powered migration capabilities as a concrete, operational practice - not just a line on a capability slide - are differentiating themselves in a market where the work is increasingly scrutinized and the pricing conversation is shifting. That differentiation translates directly into faster delivery, lower cost, reduced probability of late-stage surprises, and more defensible outcomes for clients whose data environments are regulated and complex.

The firms that navigate this moment well won't be the ones that simply talk about AI. They'll be the ones that have embedded it where delivery risk is highest - and in financial services technology programs, that starts with data.

There's a moment every software or services company knows well: the contract is signed, the deal is officially closed, and the customer is excited to get started. And somewhere in the background, a critical clock starts ticking.

Before that new customer can use your platform or services, their data has to be ingested, mapped, migrated and ready. Before your team can recognize that revenue, the customer has to be live.

That gap - between acquisition and activation - is where data migration lives. And for financial services ISVs (Independent Software Vendors), fund administrators, and BPOs (Business Process Outsourcers) managing complex client portfolios, it's also where deals get expensive, relationships start to fray, and revenue recognition gets delayed longer than anyone planned.

Understanding where data migration fits in the customer lifecycle isn't just an implementation detail. It needs to be part of your revenue strategy.

Why Financial Services Data Makes This Harder

Not all customer onboarding is created equal. In financial services - whether you're a fund administrator onboarding a new institutional client, an ISV deploying a core banking or portfolio management platform, or a BPO taking on a new asset manager's operations -- the data arriving on day one is rarely simple.

Consider what a fund administrator typically ingests when a new client comes on board: historical position data across multiple asset classes, transactions spanning years, counterparty records, NAV history, fee structures, investor allocations, and often data exported from a prior administrator's system in formats that weren't designed for portability. Each element carries its own schema, its own quirks, and its own potential for discrepancy.

Layer on the operational context - multiple accounting bases, multiple base currencies, complex instrument types like securitized products, private equity, and alternatives -- and what looks like a single "data migration" becomes dozens of concurrent mapping challenges, each carrying downstream consequences if something is off.

In financial services, a data error isn't just a technical problem. It's a client trust problem. A calculation is wrong, an allocation doesn't reconcile, a NAV is misstated. The stakes make accuracy non-negotiable -- and that's exactly what makes speed and rigor so difficult to achieve simultaneously.

This is the environment in which ISVs and service managers are trying to compress onboarding timelines. The complexity isn't going away -- but the tools available to manage it have changed. See how AI-powered data conversion works end-to-end.

The Revenue Connection Most Teams Don't Talk About

For SaaS and subscription-based software companies, the revenue model is simple on paper: recurring revenue starts when the customer is live. But the path to live runs directly through data migration.

Two things happen when that migration drags:

• Revenue recognition is delayed. In many deals, billing starts at go-live -- not at signature. Every week that the migration takes longer than planned is a week of revenue that hasn't landed yet. For a fund admin deploying a new client relationship with complex multi-asset data, that delay can extend for months.

• Customer satisfaction erodes before the relationship even begins. The client just made a significant commitment to your platform. A slow, opaque, error-prone onboarding experience sets a damaging tone -- and in financial services, where trust is the foundation of every client relationship, that damage is hard to undo.

The average data migration involves dozens -- sometimes hundreds -- of hand-offs between source data, mapping logic, and target system requirements. Every hand-off is time. Every delay is cost. And every frustration belongs to your customer.

For organizations that onboard new clients repeatedly -- ISVs with subscription models, BPOs onboarding asset managers at scale, fund administrators adding new institutional mandates -- the compounding effect is significant. Slow migrations don't just affect one deal. They affect your team's capacity, your revenue forecast, and your reputation in a market where word travels fast.

Why Data Migration Takes Longer Than It Should

The challenge isn't that organizations don't know data migration matters. It's that the process itself is inherently challenging -- especially in financial services, where two root causes compound each other:

• Data is unpredictable. Clients arrive with incomplete documentation, inconsistent formats, unknown data definitions, and data quality issues that only surface once you start looking. In fund administration, this often means discovering mid-project that a prior administrator's NAV history is stored in a non-standard format, or that position data across asset classes uses different identifier schemes. What appears to be a clean export from the source system rarely maps cleanly to the requirements of the target.
• Migrations rely on manual judgment and inputs at every step. Without AI-driven tools, mapping and transforming data -- figuring out what goes where and how it needs to be shaped -- is a largely manual process. Business analysts toggle between spreadsheets, databases, and load files, making educated guesses and waiting for feedback. In financial services, where precision matters and every field has downstream implications for calculations, reporting, and compliance, that process can feel painstaking even when the team is experienced.

The result is a process that's slow, error prone, and difficult to scale.

How AI Changes the Math on Client Onboarding

AI-powered data migration tools change the fundamental economics of onboarding by automating the steps that typically consume the most time, encouraging logic accuracy through iterative cycles, and by bringing intelligence to the parts of the process that have historically required expensive expertise.

In a financial services context, this matters in specific, tangible ways:

• Data profiling at the outset surfaces the scope of quality issues -- completeness rates by field, distribution of values, currency codes, unique values -- before the project is deep into execution. For a fund admin taking on a new client with years of historical data across multiple asset classes, this early visibility is the difference between a realistic timeline and a project that keeps slipping.

• Predictive field mapping removes what is typically the most manual, time-intensive step at the start of any onboarding. Rather than building from a blank spreadsheet, teams begin with AI-generated predictions -- ranked by confidence, flagged for review -- turning weeks of setup into a validation exercise from day one.
• AI-assisted transformation handles the rules that financial data requires: reformatting identifiers, standardizing currency codes, reconciling accounting bases, applying calculation logic consistently across thousands of records. What would otherwise require a systems engineer can be handled by a business analyst with the right tooling.

• Connected platform intelligence is what makes speed repeatable. Because every step shares active metadata -- profiling informs mapping, mapping informs transformation, transformation informs testing -- nothing is re-explained between stations. For ISVs and BPOs with recurring onboarding needs, each new client moves through the same factory: same stations, same logic, same reliable output.

Zengines customers report accelerating data migrations by up to 80%, with business analysts working 6x faster -- without needing to bring in expensive engineering resources at every step.

That speed has a direct revenue translation. Faster go-live means faster billing. Fewer iterations means lower project cost. And a smooth, well-managed onboarding experience builds client confidence from day one -- which in financial services is not just a nice-to-have, it's the foundation of a long-term profitable relationship.

Built for Teams That Do This Again and Again

Repeatability is where the economics of AI-powered migration compound. For organizations that onboard clients regularly -- fund admins adding new mandates, ISVs growing their subscriber base, BPOs managing a steady flow of transitions -- the platform's connected intelligence doesn't reset between engagements. Profiling templates carry forward. Mapping predictions sharpen. Transformation logic built for one client becomes the foundation for the next.

The result is a factory, not a one-time build. Every new client moves through the same connected stations -- the same profiling, the same mapping intelligence, the same transformation framework -- producing consistent, reliable output at a pace that scales with the business rather than against it.

For ISVs managing subscription revenue, this means a meaningful reduction in the cost of new client acquisition. For BPOs and managed service providers, it means higher margin on every engagement. For fund administrators competing on operational excellence, it means a demonstrably faster, more accurate onboarding experience -- one that becomes a differentiator when competing for mandates from institutional investors who have seen poor transitions before and are paying close attention.

Once data is live, a related challenge in financial services is proving it arrived correctly -- especially for regulated institutions. Post-migration reconciliation is the phase where confidence is either built or broken, and where regulatory obligations are met or missed.

What This Means for Your Revenue Model

Revenue recognition is ultimately about time to value. The faster a client is live, the faster they realize the benefit of your platform or service -- and the faster your revenue cycle closes. Data migration is one of the most controllable variables in that equation.

The organizations winning on this front aren't necessarily those with the cleanest client data. They're the ones who have invested in tools and processes that make migration predictable, scalable, and fast -- regardless of what the source data looks like when it arrives. In financial services, where client data is inherently complex and the margin for error is narrow, that investment pays dividends on every deal.

Whether you're an ISV accelerating client onboarding into a financial platform, a fund administrator managing recurring mandates, or a BPO building a repeatable data ingestion practice -- treating data migration as a strategic capability, not just an onboarding task, is the difference between a revenue model that scales and one that stalls.

Boston, MA - March 4, 2026 - Zengines, an AI technology company specializing in data migration and mainframe and AS400 data lineage, today announced it has been selected to demo live at FinovateSpring 2026, taking place May 5–7 in San Diego, California.

Finovate is one of the most prestigious fintech event series, drawing over 1,200 senior-level executives from banks, credit unions, and financial institutions - including nine of the top 10 U.S. banks. Demo slots are awarded through a competitive application and selection process, with only the most innovative and market-ready fintech companies earning a spot on stage.

Zengines will use its seven-minute live demo - Finovate's signature format - to showcase its Data Lineage product: an AI-powered research and visualization tool purpose-built for large financial institutions managing the complexity of “black box” systems.

What sets Zengines apart? Traditional lineage tools show you the map - at the surface level. Zengines gives you the map and the context behind it - built exclusively for the decades-old COBOL, RPG, and PL/1 systems no one fully understands anymore.

Conventional tools produce technically accurate data flow diagrams. They cannot tell you why a calculation exists, what business rule drives it, or what it means for your regulatory obligations. That context is buried in the code itself - and Zengines is built to surface it.

Two things define the Zengines platform:

1. Contextual lineage - Beyond data flow, Zengines captures the intent embedded in legacy code: calculation logic, branching conditions, field-level relationships, and business rules across thousands of modules. Raw lineage becomes actionable intelligence.

2. Legacy-codebase focus - Zengines specifically targets COBOL, RPG, and PL/1: the systems where the stakes are highest. Decades of accumulated business logic. Subject matter experts retiring faster than institutions can document what they know. No individual holds the full picture - and that risk is growing.

Together, these enable three outcomes financial institutions are struggling to achieve today:

• Regulatory compliance - Generate audit-ready lineage evidence for CDE, BCBS-239, and ORSA quickly and accurately
• Safe modernization - Reverse-engineer the "why, where, and how" of legacy code before migrating or replacing systems
• Live system confidence - Know your mainframe well enough to manage it: supporting teams, answering questions, and making changes with certainty

"Being selected to demo at Finovate is a meaningful validation of what we've built," said Caitlyn Truong, CEO and Co-Founder of Zengines. "The financial institutions in that room are dealing with exactly the challenges our lineage tool was designed to solve - regulatory mandates, modernization programs, and the 'black box' problem of legacy systems that no one can fully see into. We're excited to show them that contextual lineage is what actually moves the needle."

“Finovate demos are about showing, not telling, and Zengines’ contextual data lineage is something that I’m sure our audience is going to really appreciate seeing at FinovateSpring this May,” said Greg Palmer, VP and Host of Finovate. "The FI’s in our audience are wrestling with legacy infrastructure that's been accumulating complexity for decades. Zengines' ability to understand what's inside those systems before trying to modernize them or meet regulatory requirements is exactly the kind of solution that is likely to resonate with them.”

The Zengines Data Lineage tool is currently deployed at several Fortune 100 financial institutions across codebases spanning hundreds of thousands of source modules and tens of millions lines of code, where teams use it at enterprise scale  to accelerate analysis that previously took months down to minutes.

FinovateSpring 2026 will feature RegTech, AI, data optimization, and risk management among its key themes - making it an ideal stage for Zengines to connect with the financial institutions and consulting partners navigating solutions to support these exact priorities.
