Re-engineering and Migration

In the face of rapid advances in information technology and changing business needs, leading organizations are recognizing the benefits of evolving their organizational systems and practices. Companies are increasingly beginning to re-engineer existing business systems or are updating their technology environments and migrating to leading technology platforms. The need of the hour is for enterprises to not just migrate legacy systems and applications to the latest technologies, but also to simultaneously evolve their organizational processes and ensure that they are ably supported by these technologies.

Tata Infotech has developed solutions in re-engineering and migration that enable enterprises to integrate data from legacy systems with the latest technologies and support business operations across the enterprise. Domain experts with extensive industry background make it easier to understand and evaluate your needs in re-engineering and migration, and assist you in translating your business requirements into technology solutions.


Web-enabling of Legacy applications

Tata Infotech provides web-enabling solutions on IBM mainframe/AS/400 applications. The web-enabling solutions provide legacy applications with an intuitive browser-based user interface by introducing changes only at the screen level and leaving the host-based functionality untouched. It provides a solution that is secure and highly accessible over the Internet, and that too in a cost-effective manner.

Web Enablers

  • Lite Version: (web-enables applications with the look and feel of a terminal in a browser)
  • Lite Version with GUI: (web-enables applications with a GUI and minimal rewrite of applications)
  • Complete Solution: (web-enables existing applications and/or introduces a new application solely for the web while simultaneously interacting with old applications and databases)

Tata Infotech has experience in web-enabling applications using a host of tools:

  • IBM Host Access Transformation Server (HATS)

  • IBM Host On-Demand
  • IBM Host Publisher
  • IBM WebFacing Tool
  • Microsoft Host Integration Server

Architecture Migration
Migration of applications to a new architecture such as client server or multi-tier architectures.

Code Conversion
Upgradation of applications to new environments and versions.

The Tata Infotech Advantage

  • Over 220 man-years of experience in re-engineering applications for customers across the world.
  • Infrastructure to undertake re-engineering projects on a wide range of software environments: COBOL, Mapper, LINC, CSP, Fortran, Oracle, C and Natural, on platforms like Unisys, IBM, DEC, UNIX, HP3000, Wang and open platforms.
  • A Track Methodology (explained below) that caters to the spectrum of re-engineering services and is flexible for execution of critical phases, on-site or offshore.
  • Established practices and processes complemented by an effective toolkit (proprietary reverse engineering tools and database drivers).
  • Connectivity to client machines which enable faster renovation and test execution.
  • Capability to set up a customer specific factory to provide flexibility and customization of re-engineering strategy, standards, procedures and tools.
  • Adoption of the ISO 9000 framework for project practices.

The TRACK ( Tata Infotech Re-engineering and Conversion Kit ) Methodology

To meet the complex task of "re-engineering" from a source technology to a destination technology, Tata Infotech has developed a robust, flexible methodology called TRACK. The methodology has been designed taking into account the diversity of re-engineering services. The methodology addresses the spectrum of typical re-engineering projects and covers the pre-proposal study phase through implementation and support. The various phases addressed in this methodology include: pre-proposal study phase, customer input package (CIP) packaging, CIP set-up and assessment of applications, re-engineering planning, re-engineering, testing, implementation, acceptance, and post-acceptance support.
