Application Conversions and Solutions

Cothern Computer Systems provides a complete, native application conversion which fully utilizes IBM System z and IBM Power Systems AIX, Linux, and IBM iplatform technologies. Our conversion methodology provides a structured approach for the initial situation analysis; technical assessment; application source code conversion; application testing and defect correction; migration and live implementation.

Each CCS conversion is an engineered solution based on client specific requirements and the existing environment and standards. We do not package an array of software products which may or may not be necessary for conversion and proper operation of the converted workload.

The Cothern application conversion advantage

  • Applications are converted to run natively in the target environment without emulation
  • Methodology focused on risk avoidance, solution simplification, and long-term satisfaction
  • Rapid time-to-cost savings is achieved while managing risk
  • Ability to rewrite application programs for target platform when conversion is not economically feasible or technically possible.
  • Utilization of existing client products, standards, and conventions
  • 100% go-live implementation success rate
  • Minimal end user training required

Application Conversion Planning Process

Our approach eliminates unnecessary emulation and middleware software products and licenses. We recommend and deploy software products only from leading vendors that are extensively supported and enhanced with current practices for system management, security, and transaction management.

The typical planning process for application conversion projects includes:

  • Determine initial application inventory source metrics and counts from client questionnaire
  • Discussion to understand the environment with application owners, application managers, developers, and infrastructure managers
  • Review of current database and file systems architecture
  • Understand system interfaces, web interfaces, and user interface applications requirements
  • Define print requirements, Advanced Function Printing, special forms and overlays, and barcode printing
  • Establish third-party software product inventory, requirements, and usage
  • Document special needs and unique requirements
  • Assess migration risk and create risk avoidance plan
  • Creating initial project plan and timeline
