Legacy Systems

TECHNOLOGY & PLATFORM CONVERSIONS OF LEGACY SYSTEMS

A large number of the world's active business applications and mission-critical functions run on legacy platforms such as mainframe, AS/400, and others. Moreover, recent technological investments and advancements in legacy platforms, by vendors such as IBM, have made it imperative for companies to maintain their legacy platforms by modernizing or migrating them.

LEGACY MODERNIZATION SOLUTIONS

CyberVision's legacy application modernization provides the following service components for legacy-mainframe and iSeries platforms:

• Service-oriented architecture
• Enterprise application integration
• Web-enabling
• Environment upgrades

LEGACY APPLICATION MODERNIZATION METHODOLOGY

To offer effective, full-scale solutions for legacy systems, CyberVision has developed a five-phased methodology for SOA-based modernization.

LEGACY APPLICATION MIGRATION

Benefits of choosing CyberVision:

• Reduce legacy system migration costs and timeframes by up to 50%.
• Reduce operating costs by 15-25%.
• Leverage investment in legacy assets.
• Reduce the risk associated with implementing new technologies.
• Increase business agility.
• Improve access to information for staff and customers.

LEGACY APPLICATION MIGRATION SERVICES

• Application Value Assessment

Our analysts assess key information about your legacy system and provide a comprehensive report that will identify the areas where actions are required.

• Migration Planning

Once the value of the legacy system is understood, we will develop a roadmap identifying key business objectives and the path to achieve them. This roadmap will highlight the risks, corroborate expected results, and ensure that the user, process, and technology issues are understood and aligned with business priorities.

• Application Migration & Data Conversion

To improve functionality while maintaining business rules, CyberVision's team can migrate your current applications to a new open systems environment.

• Re-Platforming

CyberVision makes it possible to migrate applications from one physical environment to another with minimal impact to business continuity.

• Re-Documentation

Complete and automatic documentation snapshots from many languages or databases into a web browser engine. This can be performed many times in order to keep your application's documentation up to date.

• Legacy Extension & Integration

Improve flexibility and responsiveness of your legacy systems through integration and Web-enablement.

• Complete  Migration Solutions

For complex heterogeneous environments, we provide an end-to-end solution combining re-platforming, migration, extension, and replacement.

• Managed Services

Take full control of all your IT services, managing assets, staff, and infrastructure. Services can be delivered on- or off-site, or through our network of global delivery centers.

COBOL ANALYSIS

CyberVision's legacy development teams use PC tools such as evolveIT and others to help analysts and programmers better understand complex COBOL applications.

Detailed Cobol Analysis:

• analyze relationships between all application elements;
• find missing application source and redundant code;
• live documentation including control and data flows;
• detailed impact analysis and data categorization;
• multiple interactive reports and graphical views.

Our specialists use "Cobol Analysis Instruments" to provide essential support to business critical applications.

REMODELING LEGACY SOA

CyberVision's SOA solution offers effective conversion of legacy applications into a set of flexible services, by:

• Identifying and separating the service from the client functionality;
• Identifying Internal Application APIs to be exposed;
  • Sets of procedural code that comprises an API;
  • Sets of database queries representing data to be exposed;
• Processing source code and identifying where the identified APIs are located and the dataflow to and from them;
• Synthesizing a SOA interface for the API;
  • Remote procedure calls / Services for COBOL.

We use separation of the identified service functionality and source code related to client functionality. Through the use of generated control and data flow diagrams, the service oriented source code is combined while the same is done to the client code. These sets of source code are modified so that an "API" is created for the service's functionality while the client's functionality is adapted to a new "Service API". Once the APIs are created, the service can enhance business uses of the service's functionality.

Our modernization specialists deliver highest-quality solutions. CyberVision's solutions provide powerful capabilities for remodeling legacy systems so maintaining it's services is more efficient, enabling client's IT teams to respond quickly to business or process change requests.
