Market leading organizations have been investing on IT applications over multiple years to gain and retain the cutting edge advantage. While these applications are providing the necessary return on investments, it has become very critical to maintain and enhance these applications with the dynamics of business environment. These organizations are looking for trusted IT partners to take up this ownership of getting the best advantage out of their investment on these applications.

 

Exensys, with its basic objective of partnering with their customers, takes responsibility of owning these applications and provide maintenance and enhancement services.

 

Application Support Services also extends 24x7 supports for application incident management, service management, database management, technical improvements, problem management, user administration and problem assessment.

 

 

Exensys has defined two broad categories for migration projects based on the recent trends in the industry:

 

 Technology Migration 

  Legacy applications (Visual Basic, Power Builder, C++/VC++ etc) to multi tier applications

  based on J2EE or Dot Net.

 

 Platform Migration
  Application running on old application server platforms needs to be ported to latest application

  server platforms.

 

 Consulting / Advisory Support

 Governance

 Execution and Sustenance

 

Business Challenges

 

 Higher cost in maintenance of legacy applications

 Technology limitations in legacy applications and platforms

 Adoption of open source wave

 Adoption of emerging architectural concepts

 Conversion of two tier to n tier application

 Mergers and acquisitions triggering application consolidation

 Adoption of SOA philosophy

 Lack of Vendor support for legacy applications and older platforms

 Lack of skilled resources for legacy application maintenance and development

 

At Exensys, we follow an approach that:

 

 Integrates Legacy Systems and new Internet driven technologies.

 Migrates systems and business logic to new architectures, languages and web-based

  environments.

 Ensures systems quality and stability.

 

The procedure is usually client specific, but involves the following steps:

 

 Initial analysis step allows sufficient understanding of the original application functionality

 Functional decomposition of the original application. Example: screens, reports, etc

 Selection of the defined functional components, which should be ported to the new application

 This step may require extensive discussion and agreement with the customer

 Development of the system conversion specification. This document in particular indicates

  change requirements to the original functionality and new required features

 Development of proper data conversion mechanisms allows identification of and resolution of

  data inconsistency problems

 

Core Competencies

 

 Platform migration

 

 Code parting and data migration

 Technology migration – Legacy application developed in Visual Basic, Power Builder, C++/VC++

  to application in J2EE or Dot Net
