Typically, this collection of systems consists of a variety of purchased and custom systems that were developed over a period of time. Individual components within this collection use a variety of industry-standard technologies that eventually fall out of favor and become ‘unsupported’ as they age. Additionally, infrastructure such as operating systems, server software and hardware age; they must be upgraded to take advantage of the performance and security enhancements newer versions offer.

Many organizations fall far behind industry standards and trends, allowing their systems to age to a point where they are no longer supported. The motivation for this ranges from a desire to minimize costs through fear of breaking an existing system to pure apathy. Upgrading hardware, operating systems and server software introduces significant risk that a system or interface that has worked for years will now behave in a new, unpredictable manner. Many organizations are simply too busy with day-to-day tasks to focus on systems upgrades and regression tests.

Modernizing applications often falls outside a typical software maintenance plan, because the effort involved with updating custom and purchased applications is typically much greater than applying software updates. Modernizing applications often includes data conversions and updating or re-writing data interfaces.

TrinityTG has assisted a variety of government and private organizations with upgrading individual legacy systems and whole infrastructures. These projects have ranged from simple planning efforts to complete application re-writes and regression testing.

Planning efforts entail working with management, users and technical staff to create a maintenance plan to keep purchased software up-to-date and upgrade custom software as new component versions and server software become available. Other planning efforts are multi-step plans that begin with a migration from old servers to a new data center, followed by strategic and project plans for specific hardware and software upgrades. These comprehensive plans always include regression testing of system functionality and data interfaces between individual systems. TrinityTG has successfully delivered complete application re-writes that replace aging legacy technology with the latest and greatest technology that implements industry best practices for data management, object-oriented design and development and web-based data interfaces.
