Mainframe Managed Service Providers (MSPs) have built impressive capabilities over the last several decades. They excel at infrastructure management, code conversion, and supporting complex hosting environments. Many have invested millions in advanced tools for code parsing, refactoring, and other technical aspects of mainframe management and modernization. Yet despite these strengths, MSPs consistently encounter the same bottlenecks that threaten mainframe modernization project timelines, profit margins, and client satisfaction.
In this article, we’ll explore the most common gaps MSPs face, how Zengines platform helps fill those gaps, and why Mainframe MSPs are partnering with Zengines.
The Critical Gaps in Current MSP Toolkits
Gap 1: Business Rules Discovery
While MSPs have sophisticated tools for parsing and reverse engineering COBOL code—they can extract syntax, identify data structures, and map technical dependencies—they lack capabilities for intelligent business logic interpretation. These parsing tools tell you what the code does technically, but not why it does it from a business perspective.
Current approaches to understanding the embedded business rules within parsed code require:
- Manual analysis by teams of expensive mainframe experts and business teams to interpret the business meaning behind technical code structures
- Line-by-line COBOL review to understand calculation logic and translate technical operations into business requirements
- Manual correlation between parsed code elements and actual business processes
- Expert interpretation of conditional logic to understand business rules and decision trees
- Guesswork about the original business intent behind complex branching statements and embedded calculations
Even with advanced parsing capabilities, MSPs still need human experts to bridge the gap between technical code structure and business logic understanding. This discovery phase often represents 30-40% of total project time, yet MSPs have limited tools to accelerate the critical transition from "code parsing" to "business intelligence."
The result: MSPs can quickly identify what exists in the codebase, but still struggle to efficiently understand what it means for the business—creating a bottleneck that no amount of technical parsing can solve.
Gap 2: Data Migration Tools
A critical step in any mainframe modernization project involves migrating data from legacy mainframe systems to new modern platforms. This data migration activity often determines project success or failure, yet it's where many MSPs face their biggest challenges.
While MSPs excel at physical data ETL and have tools for moving data between systems, they struggle with the intelligence layer that makes migrations fast, accurate, and low-risk:
- Manual data mapping between legacy mainframe schemas and modern system structures—a time-intensive process due to guesswork of trial-and-error
- Insufficient data quality analysis relevant to the business context, leading to "garbage in, garbage out" scenarios in the new system
- Manual transformation rule creation that requires expensive technical resources and extends project timelines
- Limited validation capabilities to ensure data integrity during and after migration
- Rules-based tools that constantly need to be adjusted when the data doesn’t fit the expected pattern - more often then not, this is the case.
These gaps expose organizations to costly risks: project delays, budget overruns, compromised data integrity, and client dissatisfaction from failed transfers. Delays and cost overruns erode margins and strain client relationships. Yet the most significant threat remains post-go-live discovery of migration mistakes. Today’s approach of manual processes are inherently time-constrained—teams simply cannot identify and resolve all issues before deployment deadlines. Unfortunately, some problems surface only after go-live, forcing expensive emergency remediation that damages client trust and project profitability.
The result: MSPs can move data technically, but lack intelligence tools to do it efficiently, accurately, and with confidence—making data migration the highest-risk component of mainframe modernization projects.
Gap 3: Testing and Validation Blind Spots
Once data is migrated from mainframe systems to modern platforms, comprehensive testing and validation becomes critical to ensure business continuity and data integrity. This phase determines whether the migration truly preserves decades of embedded business logic and data relationships.
Without comprehensive understanding of embedded business logic and data interdependencies, MSPs face significant validation challenges:
- Incomplete test scenarios based on limited business rules knowledge—testing what they assume exists rather than what actually exists in the legacy system
- Inefficient testing based on what the code presents versus what actually exists within the data
- Manual reconciliation between old and new systems that's time-intensive, error-prone, and often misses subtle data discrepancies
- Inadequate validation coverage of complex business calculations and conditional logic that may only surface under specific data conditions
- Reactive testing methodology that discovers problems during user acceptance testing rather than proactively during migration validation
- Post-go-live surprises when undocumented logic fails to transfer, causing business process failures that weren't caught during testing
The consequences: validation phases that stretch for months, expensive post-implementation fixes, user confidence issues, and potential business disruption when critical calculations or data relationships don't function as expected in the new system.
The result: MSPs have inadequate and non-optimized testing where teams test what they think is important rather than what the business actually depends on.

IBM's RPG (Report Program Generator) began in 1959 with a simple mission: generate business reports quickly and efficiently. What started as RPG I evolved through multiple generations - RPG II, RPG III, RPG LE, and RPG IV - each adding capabilities that transformed it from a simple report tool into a full-featured business programming language. Today, RPG powers critical business applications across countless AS/400, iSeries, and IBM i systems. Yet for modern developers, understanding RPG's unique approach and legacy codebase presents distinct challenges that make comprehensive data lineage essential.
The Strengths That Made RPG Indispensable
Built-in Program Cycle: RPG's fixed-logic cycle automatically handled file operations, making database processing incredibly efficient. The cycle read records, processed them, and wrote output with minimal programmer intervention - a major strength that processed data sequentially, making it ideal for report generation and business data handling.
Native Database Integration: RPG was designed specifically for IBM's database systems, providing direct interaction with database files and making it ideal for transactional systems where fast and reliable data processing is essential. It offered native access to DB2/400 and its predecessors, with automatic record locking, journaling, and data integrity features.
Rapid Business Application Development: For its intended purpose - business reports and data processing - RPG was remarkably fast to code. The fixed-format specifications (H, F, D, C specs) provided a structured framework that enforced consistency and simplified application creation.
Exceptional Performance and Scalability: RPG applications typically ran with exceptional efficiency on IBM hardware, processing massive datasets with minimal resource consumption. RPG programming language has the ability to handle large volumes of data efficiently.
Evolutionary Compatibility: The language's evolution path meant that RPG II code could often run unchanged on modern IBM i systems - a testament to IBM's commitment to backward compatibility that spans over 50 years.
The Variations That Created Complexity
RPG II (Late 1960s): The classic fixed-format version with its distinctive column-specific coding rules and built-in program logic cycle, used on System/3, System/32, System/34, and System/36.
RPG III (1978): Added subroutines, improved file handling, and more flexible data structures while maintaining the core cycle approach. Introduced with System/38, later rebranded as "RPG/400" on AS/400.
RPG LE - Limited Edition (1995): A simplified version of RPG IV designed for smaller systems, notably including a free compiler to improve accessibility.
RPG IV/ILE RPG (1994): The major evolution that introduced modular programming with procedures, prototypes, and the ability to create service programs within the Integrated Language Environment - finally bringing modern programming concepts to RPG.
Free-Format RPG (2013): Added within RPG IV, this broke away from the rigid column requirements while maintaining backward compatibility, allowing developers to write code similar to modern languages.
The Weaknesses That Challenge Today's Developers
Steep Learning Curve: RPG's fixed-logic cycle and column-specific formatting are unlike any modern programming language. New developers must understand both the language syntax and the underlying program cycle concept, which can be particularly challenging.
Limited Object-Oriented Capabilities: Even modern RPG versions lack full object-oriented programming capabilities, making it difficult to apply contemporary design patterns and architectural approaches.
Cryptic Operation Codes: Traditional RPG used operation codes like "CHAIN," "SETLL," and "READE" with rigid column requirements that aren't intuitive to developers trained in modern, free-format languages.
Complex Maintenance Due to Evolution: The evolution from RPG II (late 1960s) through RPG III (1978) to RPG IV/ILE RPG (1994) and finally free-format coding (2013) created hybrid codebases mixing multiple RPG styles across nearly 50 years of development, making maintenance and understanding complex for teams working across different generations of the language.
Proprietary IBM-Only Ecosystem: Unlike standardized languages, RPG has always been IBM's proprietary language, creating vendor lock-in and concentrating expertise among IBM specialists rather than fostering broader community development.
The Legacy Code Challenge: Why RPG Is Particularly Difficult Today
RPG presents unique challenges that go beyond typical legacy system issues, rooted in decades of development practices:
- Multiple Format Styles in Single Systems: A single system might contain RPG II fixed-format code (1960s-70s), RPG III subroutines (1978+), RPG LE simplified code (1995+), and RPG IV/ILE procedures with free-format sections (1994+) - all working together but following different conventions and programming paradigms developed across 50+ years, making unified understanding extremely challenging.
- Embedded Business Logic: RPG's tight integration with IBM databases means business rules are often embedded directly in database access operations and the program cycle itself, making them hard to identify, extract, and document independently.
- Minimal Documentation Culture: The RPG community traditionally relied on the language's self-documenting nature and the assumption that the program cycle made logic obvious, but this assumption breaks down when dealing with complex business logic or when original developers are no longer available.
- Proprietary Ecosystem Isolation: RPG development was largely isolated within IBM midrange systems, creating knowledge silos. Unlike languages with broader communities and extensive online resources, RPG expertise became concentrated among IBM specialists, limiting knowledge transfer.
- External File Dependencies: RPG applications often depend on externally described files (DDS) where data structure definitions live outside the program code, making data relationships and dependencies difficult to trace without specialized tools.
Making Sense of RPG Complexity: The Data Lineage Solution
Given these unique challenges - multiple format styles, embedded business logic, and lost institutional knowledge - how do modern teams gain control over their RPG systems without risking business disruption? The answer lies in understanding what your systems actually do before attempting to change them.
Modern data lineage tools provide exactly this understanding by:
- Analyzing all RPG variants within a single system, providing unified visibility across decades of development spanning RPG II through modern free-format code.
- Mapping database relationships from database fields through program logic to output destinations, since RPG applications are inherently database-centric.
- Discovering business rules by analyzing how data transforms as it moves through RPG programs, helping teams reverse-engineer undocumented logic.
- Assessing impact before making changes, identifying all downstream dependencies - crucial given RPG's tight integration with business processes.
- Planning modernization by understanding data flows, helping teams make informed decisions about which RPG components to modernize, replace, or retain.
The Bottom Line
RPG systems represent decades of business logic investment that often process a company's most critical transactions. While the language may seem archaic to modern eyes, the business logic it contains is frequently irreplaceable. Success in managing RPG systems requires treating them not as outdated code, but as repositories of critical business knowledge that need proper mapping and understanding.
Data lineage tools bridge the gap between RPG's unique characteristics and modern development practices, providing the visibility needed to safely maintain, enhance, plan modernization initiatives, extract business rules, and ensure data integrity during system changes. They make these valuable systems maintainable and evolutionary rather than simply survivable.

When Grace Hopper and her team developed COBOL (Common Business-Oriented Language) in the late 1950s, they created something revolutionary: a programming language that business people could actually read. Today, over 65 years later, COBOL still processes an estimated 95% of ATM transactions and 80% of in-person transactions worldwide. Yet for modern development teams, working with COBOL systems presents unique challenges that make data lineage tools absolutely critical.
The Strengths That Made COBOL Legendary
English-Like Readability: COBOL's English-like syntax is self-documenting and nearly self-explanatory, with an emphasis on verbosity and readability. Commands like MOVE CUSTOMER-NAME TO PRINT-LINE or IF ACCOUNT-BALANCE IS GREATER THAN ZERO made business logic transparent to non-programmers, setting it apart from more cryptic languages like FORTRAN. This was revolutionary - before COBOL, business logic looked like assembly language (L 5,CUSTNAME followed by ST 5,PRINTAREA) or early FORTRAN with mathematical notation that business managers couldn't decipher.
Precision Decimal Arithmetic: One of COBOL's biggest strengths is its strong support for large-precision fixed-point decimal calculations, a feature not necessarily native to many traditional programming languages. This capability helped set COBOL apart and drive its adoption by many large financial institutions. This eliminates floating-point errors critical in financial calculations.
Proven Stability and Scale: COBOL's imperative, procedural and (in its newer iterations) object-oriented configuration serves as the foundation for more than 40% of all online banking systems, supports 80% of in-person credit card transactions, handles 95% of all ATM transactions, and powers systems that generate more than USD 3 billion of commerce each day.
The Weaknesses That Challenge Today’s Teams
Excessive Verbosity: COBOL uses over 300 reserved words compared to more succinct languages. What made COBOL readable also made it lengthy, often resulting in monolithic programs that are hard to comprehend as a whole, despite their local readability.
Poor Structured Programming Support: COBOL has been criticized for its poor support for structured programming. The language lacks modern programming concepts like comprehensive object orientation, dynamic memory allocation, and advanced data structures that developers expect today.
Rigid Architecture and Maintenance Issues: By 1984, maintainers of COBOL programs were struggling to deal with "incomprehensible" code, leading to major changes in COBOL-85 to help ease maintenance. The language's structure makes refactoring challenging, with changes cascading unpredictably through interconnected programs.
Limited Standard Library: COBOL lacks a large standard library, specifying only 43 statements, 87 functions, and just one class, limiting built-in functionality compared to modern languages.
Problematic Standardization Journey: While COBOL was standardized by ANSI in 1968, standardization was more aspirational than practical. By 2001, around 300 COBOL dialects had been created, and the 1974 standard's modular structure permitted 104,976 possible variants. COBOL-85 faced significant controversy and wasn't fully compatible with earlier versions, with the ANSI committee receiving over 2,200 mostly negative public responses. Vendor extensions continued to create portability challenges despite formal standards.
The Legacy Challenge: Why COBOL Is Hard to Master Today
The biggest challenge isn't the language itself - it's the development ecosystem and practices that evolved around it from the 1960s through 1990s:
- Inconsistent Documentation Standards: Many COBOL systems were built when comprehensive documentation was considered optional rather than essential. Comments were sparse, and business logic was often embedded directly in code without adequate explanation of business context or decision rationale.
- Absence of Modern Development Practices: Early COBOL development predated modern version control systems, code review processes, and structured testing methodologies. Understanding how a program evolved - or why specific changes were made - is often impossible without institutional knowledge.
- Monolithic Architecture: COBOL applications were typically built as large, interconnected systems where data flows through multiple programs in ways that aren't immediately obvious, making impact analysis extremely difficult.
- Proprietary Vendor Extensions: While COBOL had standards, each vendor added extensions and enhancements. IBM's COBOL differs from Unisys COBOL, creating vendor lock-in that complicates understanding and portability.
- Lost Institutional Knowledge: The business analysts and programmers who built these systems often retired without transferring their institutional knowledge about why certain design decisions were made, leaving current teams to reverse-engineer business requirements from code.
Why Data Lineage Is Your COBOL Lifeline
This is where modern data lineage tools become invaluable for teams working with COBOL systems:
- Automated Documentation: Lineage tools can map data flows across hundreds of COBOL programs, creating the documentation that was never written
- Impact Analysis: Before making changes, teams can see exactly which programs, files, and downstream systems will be affected
- Business Context: By tracing data from source to consumption, teams can understand the business purpose behind complex COBOL logic
- Risk Reduction: Visual data flows help prevent the costly mistakes that come from modifying poorly understood legacy systems
The Bottom Line
COBOL's deep embedding in critical business processes represents a significant business challenge and risk that organizations must address. Success with COBOL modernization - whether maintaining, replacing, or transforming these systems - requires treating them as the complex, interconnected ecosystems they are. Data lineage tools provide the missing roadmap that makes COBOL systems understandable and manageable, enabling informed decisions about their future.
The next time you make an online payment, remember: there's probably COBOL code processing your transaction. And somewhere, a development team is using data lineage tools to keep that decades-old code running smoothly in our modern world.

Mainframe modernization projects represent some of the highest-stakes technology initiatives an organization can undertake. These systems run critical business operations, store decades of institutional knowledge, and process millions of transactions daily.
Yet despite billion-dollar budgets and multi-year timelines, modernization projects fail at alarming rates—not because the technology is impossible to replace, but because teams make predictable, avoidable mistakes during planning and execution. The difference between a successful modernization that delivers ROI and a failed project that wastes millions often comes down to understanding these critical pitfalls before they derail your initiative. Here are the five biggest mistakes organizations make in mainframe modernization—and how to avoid them.
#1: Underestimating embedded complexity
Mainframe systems combine complex data formats AND decades of embedded business rules that create a web of interdependent complexity. VSAM files aren't simple databases - they contain redefinitions, multi-view records, and conditional logic that determines data values based on business states. COBOL programs embed business intelligence like customer-type based calculations, regulatory compliance rules, and transaction processing logic that's often undocumented.
Teams treating mainframe data like standard files discover painful surprises during migration when they realize the "data" includes decades of business logic scattered throughout conditional statements and 88-level condition names. This complexity extends to testing: converting COBOL business rules and EBCDIC data formats demands extensive validation that most distributed-system testers can't handle without deep mainframe expertise.
#2: Delaying dependency discovery
Mainframes feed dozens of systems through complex webs of middleware like WebSphere, CICS Transaction Gateway, Enterprise Service Bus, plus shared utilities, schedulers, and business processes. The costly mistake is waiting too long to thoroughly map all these connections, especially downstream data feeds and consumption patterns.
Your data lineage must capture every system consuming mainframe data, from reporting tools to partner integrations, because modernization projects can't go live when teams discover late in development that preserving these data feeds and business process expectations requires extensive rework that wasn't budgeted or planned.
#3: Tolerating knowledge bottlenecks
Relying on two or three mainframe experts for a million-line modernization project creates a devastating traffic jam where entire teams sit idle waiting for answers. Around 60% of mainframe specialists are approaching retirement, yet organizations attempt massive COBOL conversions with skeleton crews already stretched thin by daily operations.
Your expensive development team, cloud architects, and business analysts become inefficient and underutilized because everything funnels through the same overworked experts. The business logic embedded in decades-old COBOL programs often exists nowhere else, creating dangerous single points of failure that can derail years of investment and waste millions in team resources.
#4: Modernizing everything indiscriminately
Organizations waste enormous effort converting obsolete, duplicate, and inefficient code that should be retired or consolidated instead. Mainframe systems often contain massive amounts of redundant code - programs copied by developers who didn't understand dependencies, inefficient routines that were never optimized, and abandoned utilities that no longer serve any purpose. Research shows that 80% of legacy code hasn't been modified in over 5 years, yet teams spend months refactoring dead applications and duplicate logic that add no business value.
The mistake is treating all millions of lines of code equally rather than analyzing which programs actually deliver business functionality. Proper assessment identifies code for retirement, consolidation, or optimization before expensive conversion, dramatically reducing modernization scope and cost.
#5: Starting without clear business objectives
Many modernization projects fail because organizations begin with technology solutions rather than business outcomes. Teams focus on "moving to the cloud" or "getting off COBOL" without defining what success looks like in business terms. According to research, 80% of IT modernization efforts fall short of savings targets because they fail to address the right complexity.
The costly mistake is launching modernization without stakeholder alignment on specific goals - whether that's reducing operational costs, reducing risk in business continuity, or enabling new capabilities. Projects that start with clear business cases and measurable objectives have significantly higher success rates and can demonstrate ROI that funds subsequent modernization phases.
Ready to modernize with confidence?
Mainframe modernization doesn't have to be a gamble. The organizations that succeed are those that proactively address complexity, map dependencies early, democratize knowledge, focus on business value, and align around clear objectives from day one. These aren't just best practices—they're the difference between transformation projects that deliver measurable ROI and those that become cautionary tales.
The good news? Modern data lineage and AI-powered analysis tools can help you avoid all five of these mistakes, giving your team the visibility and intelligence needed to de-risk your modernization initiative before investing millions in execution.
Schedule a demo with Zengines to see how AI-powered mainframe data lineage can accelerate your modernization while reducing risk, cost, and reliance on scarce expertise.
