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.
Offerings:
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:
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

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.
