Fortune 500 Financial Management Group
(TRANSACT/4GL and VPLS to .NET - CORE Directed Migration)

A large Fortune 500 Financial Management Group based in the Eastern USA relies heavily on a financial accounting system written in VPLUS, TRANSACT/4GL and COBOL running against an IMAGE database to manage all aspects of its Retirements Fund System. Built in the early 1980’s, this system is a character-based application that runs on HP e3000 servers. The system supports thousands of users across the USA. After looking at four alternatives for its application migration – buy, build and two variants of migrate – the organization selected CORE to manage the migration process from start to finish.

The organization chose CORE Migration automated TRANSACT/4GL to .NET solution because of CORE’s expertise with TRANSACT/4GL, VPLUS and its proven technology in migrating TRANSACT/4GL and VPLUS forms to a modern .NET platform. In addition, CORE’s Renaissance Architect™ Frame­work guaranteed the organization that 100% of the Retirement Funds system’s existing functionality would be preserved while providing flexibility for future enhancements and customizations. CORE Migration’s automated migration process and training provided the organization with a low risk and cost-effective alternative to buy or build.

South Orange County Community College District
(PowerHouse® - CORE Directed Migration)

South Orange County Community College District (SOCCCD) looked at two alternatives – buy and migrate - for its one of the key administrative applications. SOCCCD selected CORE Migration to migrate its Human Resources System (HRS). Built in the 1980s, the HRS is a character-based, custom application using Cognos PowerHouse® and running on HP VAX OpenVMS servers. The information associated with over 2,000 employees is managed in the HRS which tracks the movement of every employee within the District. Some of the sub systems include key functions such as budgeting, personnel, payroll, health and safety and security.

The CORE Migration team completed the database migration from RMS (non-relational) and RDB on the OpenVMS to Microsoft SQL Server 2005 on Windows. Transact SQL procedures were created in order to update data in the underlying database. CORE ensured SOCCCD’s IT staff who are responsible for the maintenance and enhancements of the migrated application were fully trained and confident with CORE’s Renaissance Architect™ development tools.

“The CORE Migration team really impressed us. Not only were they consistently responsive, but their approach was practical and the depth of their technical knowledge made us all feel very confident in the success of the migration.”

Jim Laurie, Human Resources Information Systems Manager, SOCCCD

Glassman Consulting Group.
(PowerHouse® - Self-Directed Migration)

After considering several buy, build and migrate alternatives, Glassman Consulting Group selected CORE Migration to migrate an insurance claim system from Cognos PowerHouse and running on HP e3000 servers to Microsoft® .NET 2005 running against a SQL Server database on a Windows platform. Glassman’s client, a medium sized, international insurance company, relies on the information associated with over 250,000 medical benefit claims and payments is managed in the system. Approximately 120 end-users located at three sites use the application internally.

The CORE team completed the database migration from Image (non-relational) on the HP-3000 to Microsoft SQL Server 2005 on Windows. Transact SQL procedures were created in order to update data in the underlying database. The new environment is Microsoft .NET 2005 using the Renaissance Architect framework for .NET as developed by CORE. CORE was responsible for leading and supporting the Glassman team in developing the new business application using the Microsoft .NET Renaissance Architect framework coupled with the system development life cycle (SDLC).

“We explored other alternatives, but chose CORE because they offered the right technology, process and tools. CORE’s workbench of software tools combined with the team’s depth of expertise in PowerHouse provided us with a high degree of confidence that the migration would be successful.” Bobbie Glassman, President, Glassman Consulting Group
