Legacy Modernization and Migration

In the present-day economy the key differentiators for any organization are Speed, Collaboration, and Innovation. To keep pace with the highly volatile marketplace, organizations need business applications that are highly flexible and easily accessible to internal and external stakeholders. Mainframe host-based systems typically define and control the majority of business processes in large organizations. Enterprises that can effectively leverage their legacy systems are best positioned for growth and success.

TSI’s application modernization services help renovate legacy systems to enhance flexibility, alleviate risk, minimize disruption and lower costs. We enable you to address legacy system issues such as multiple technology platforms, high cost of maintenance, unsupported systems, shrinking employee expertise, lack of integration and web capabilities.

TSI’s specialized teams are able to put together the application blueprint for the entire organization, identify specific problem areas and work toward streamlining the applications portfolio into a more efficient and robust setup. In the process the client also saves significant costs and enjoys higher reliability and up-time of the rationalized portfolio of applications. We deliver portfolio rationalization and modernization using a well-defined framework, best practices and proven capabilities in legacy. Our services include applications portfolio assessment, rationalization roadmap creation, platform migration, application modernization and data modernization.

Legacy Re-engineering

There are very few successful businesses that can operate the same business model or even maintain the same organizational structure as they mature and their business grow (or even shrink).

Periodic reviews or the status quo of the business versus the business plan and strategy are necessary to ensure that the organization is positioned to meet its objectives whilst keeping up with resource desires and motivators.

Senior managers are often reluctant to acknowledge the need for such change, however by bringing an independent consultant in to ‘own’ a reengineering project all stakeholders are assured of an independent view for where the company could be going.

Reengineering involves adopting a completely new architecture and technology whilst retaining the core business functionality of the existing application. The complexity in such projects is that the business rules are frequently embedded in huge legacy systems written decades ago. Over the years, many such applications lose their relevance in the context of changing business environment.

Applications that were custom developed in the past and modified from time to time without keeping the documentation updated also lead to another set of problems. All of this leads to avoidable high costs of application maintenance and also add to the risk of outages with serious consequences as old applications are unable to stay adept with changing requirements or are unable to interface with new systems.

When it is considered that over 80-85% of the core business rules may not change, adopting the traditional development route makes the entire project highly expensive and risk prone.

TSI works within your brief and consults various levels across the organization to ensure the process is accepted, beneficial and as least disruptive as possible whilst taking it a step further to manage the transformation and change together with you.

TSI follows a widespread re-engineering methodology that is flexible for individual situations. The business rules extracted from the legacy systems are used as foundation to derive the business rules and requirements for the new system. The entire environment is established, ensuring that requirements are not neglected in the new system.

Upon release of the finalized requirements for the new system, a Re-engineering of the complete end-to-end solution is undertaken. This solution offers re-engineering of presentation, business logic, and data from the legacy environment to an open, business-driven, flexible target environment. UI and workflow typically changes completely in the new system. This approach brings in the advantages of legacy comprehension in terms of retaining and reusability of legacy system business rules along with the flexibility to move forward with the latest state-of-the-art technology/platform options based on the principles of the SOA architecture.

Legacy Migration

Application Migration provides the solution for platform rationalization in the form of either upgrades or completely switching over to a new language or database or platform.  With the fast changing business scenarios, organizations globally are faced with challenges requiring them to upgrade their applications and/or legacy systems with the latest technologies. Application Migration quickly and efficiently moves applications to modern platforms with the latest architectures and designs while preserving original goals and application logic.

In a migration approach, in most cases, the prime focus is on the database access logic rather than the entire application logic. The key thing in migration is impact assessment and degree of process automation. Depending on the findings of the Assessment Study a combination of migration and re-engineering may be required.

Legacy Web Enablement

Web enablement extends the life of your legacy applications by providing a web enabled interface. The rapid advancements in web application technologies make it easier than ever to build updated, full-featured UI for web enabling your legacy applications. With the right tools this approach is also extremely useful in building new applications for your mobile workforce.

The existing legacy system stays integral with all the inherent business logic. This solution provides major benefits to the clients such as security, user-friendliness, quick turnaround-time, and cost. As the application is kept intact, the security subsystem built in the application also remains integral to help reduce the possible risks of a security breach for mission-critical systems. The web-enabled interfaces use graphics and other visual components to enhance the look and feel of the system, thus improving the usability of the system. Such projects enable effective and secured e-Business and Internet computing and are executed with low turnaround time.
