Moving from legacy monoliths to next-gen
cloud native platforms


Businesses today are facing increased competitive pressures to get the most out of their existing IT assets and continuously optimize to meet the demands of the changing market, reduce technical debt and increase productivity. Archaic applications limit the ability to innovate and pose the following challenges:

  • Monolithic design – Existing core systems are designed to tightly couple data, workflows and embedded rules. This makes them inflexible, creates a need for system wide regression testing upon any changes, and does not support new business process models that leverage the latest technological advancements
  • Lack of knowledge – Work done on applications by multiple subject matter experts over many years is lost due to attrition or workforce aging. The business logic, data flows and dependencies cannot be easily extracted from code or older documentation
  • Complex integration – Legacy monolithic applications have complex integrations between modules, requiring complex testing and production implementation effort, and delayed time-to-market
  • High cost of maintenance – Cost of maintaining older applications becomes prohibitive, mainly due to shrinking expert resource pools

This calls for application modernization of existing legacy architecture to next-generation cloud native platform architecture.



Enterprises continuously strive to provide their customers and stakeholders with personalized experiences, enter markets with new business models, release products in an accelerated manner, and scale their businesses infinitely. Our sustainable, continuous application modernization program focuses on applying tools, approaches and best practices to extract and transition legacy capabilities and workloads, delivering business benefits that come from cloud native architectures and modern platform ecosystems.


Deconstruct legacy applications.

Deconstruct legacy applications in self-funded increments, with minimal IT overhead to manage change and reduce technical debt. This helps optimize spend on modernization while continuously delivering real business benefits.

Simultaneously modernize applications and optimize.

Simultaneously modernize applications and optimize maintenance costs and efforts. This approach reduces total cost of ownership, offers near-immediate responses to business needs, and rationalizes and modernizes an enterprise’s application portfolio.

Leverage years of accumulated domain

Leverage years of accumulated domain and technology experiences to automate many aspects of the modernization process.

Extract legacy business logic

Extract legacy business logic into modeling software, which goes into domain-driven design for microservices.

Recover knowledge

Recover knowledge that goes into automation frameworks to build end state ecosystems.

These methods offer businesses cloud-native microservices based capabilities, disposable architecture ecosystems that allow for continuous technology and capability innovation, and highly automated IT development and operations that help in optimizing build and run.








We help our clients modernize monolithic applications written on IBM Z® and IBM i operating systems, legacy distributed applications written on Visual Basic, Delphi, PowerBuilder, Oracle Forms, MS Access, 4GLs and older architecture (3 tier, SOA, MVC) to next-gen cloud native architectures (12 factor, Docker, serverless, Kubernetes, microservices, event-driven) running on Amazon AWS, Microsoft Azure, Google Cloud Platform, IBM RedHat OpenShift, VMWare Tanzu Application Server. We utilize combinations of approaches in the journey to application modernization including rehost, replatform, replace, refactor, rearchitect, rebuild, retain and retire. Batch and online applications and data are migrated and modernized through methods such as emulation, containerization, APIfication, automated code conversion, business rules extraction, automated code generation, automated deployment, data externalization, etc.

Mphasis accelerates application modernization for global clients with its robust set of tools for modernization, migration and cloud native development. The Mphasis NextSTEP™ Platform provides numerous integrated IP for various services offered.


Modernization Acceleration

  • Next Gen Transformer (NGTrans) automatically extracts user interface patterns, business logic and data logic from legacy applications, and maps them to the target environment and architecture. The tool then generates target code blocks for the new environment.
  • Source Object and Code Analyzer (SOCA) is an automated source object and code analyzer tool for Visual Basic 6, C++, FORTRAN, Oracle Forms, PowerBuilder, Delphi, and COBOL. It works with code that are compiled without any errors and generates customized MIS reports for code stacks within the area of application assessment and sizing. SOCA ensures minimal effort in sizing legacy applications and provides immediate response to clients.
  • COBOL Explorer, Analyzer and Documenter (CEAD) is a code analyzer, explorer, and documenter for Mainframe COBOL. These documents could be used for the purpose of application modernization, deploying the rules in other platforms and of course for maintenance and enhancement.


Migration Acceleration

  • KRYPTON™ Composable Cloud Migration and Modernization Platform - With an automation-first and DevSecOps-led approach to migration and modernization, Mphasis Krypton™ enables enterprises to achieve large scale migrations in a faster and more secure manner with optimized cost of run.
  • Containerization Migration Automation Suite (CMAS) provides ability to perform end to end assessment at application level, supported by an inbuilt recommendation engine. Based on assessment outcomes, it creates Docker images for the application.
  • Cloud Migration Assistant (CMA) offers the ability to automate cloud migration readiness assessments. Based on vital parameters captured, it Is a flexible and robust tool that can accommodate the assessment needs of a customer for any number of applications in their portfolio and produce application readiness (Go or No Go) to migrate to cloud, potential remediation type and potential groups (waves) for migration.
  • Pharos for Discovery Analysis and Visualization. Pharos helps perform cloud migration assessments quickly and create migration plans.
  • Navigator Orchestrates, monitors and reports cloud migration activities. It connects to Pharos for taking migration planning inputs. It integrates with other migration tools provided by AWS and Azure.


Cloud Native Development

  • Microservices Composer helps build the foundation platform for any microservices based application that can be readily deployed on multiple container platforms such as Docker Swarm, Kubernetes and PCF. The associated application composer portal is a web-based tool to choose the required services for an application in an intuitive way.
  • Microservices Testing Framework (MSTF) helps end-users to test microservices in a very simple 3-steps clicks and also allows discovery of SOAP based web services and RESTful services. Seamless backend API services connectivity with flexible, scalable and secure setup models as on-premises and cloud environments.
  • AutoCode.AI is a deep learning framework to automate the design-to-code front-end GUI development process, reducing the time, cost and effort to go from requirements to code. Leverages cloud formation templates and containers to host and manage the code for quick validation.


Data Migration

  • Data Migration Engine (DME) migrates data from source data store to target data store for any business application based on the attribute mappings. The data source and target can be of any technology. The engine also does data validation, data translation and transformation based on the supplied business logic. The tools also provide the ability to run the complete migration of the application data in one single batch and dry runs for validating the data and for doing data corrections.
  • Data Migration Toolkit (DMT) Automated Database Migration framework and scripts for dumping data by unloading using native utilities and load data in target using native load scripts (DB2 to Oracle , SQL Server etc.) and can be customized for any relational database.
