Companies often maintain old applications in order to retain and access data from legacy systems because there is a fear of loss of information, lack of lineage or anxiety over legal retribution. These legacy systems can become a burden and therefore need to be considered either a financial asset or debt. Some of the challenges encountered are redundant capabilities with software, especially as what is acquired and repurposed by larger vendors. These information systems are written in a variety of programming languages on divergent operating systems and represent incompatible interfaces. Additionally most applications bear a maintenance cost. Finally and of most interest to data professionals is the information locked up in these legacy systems still represents a part of a company's information portfolio.

This session is designed to walk through steps to preserve important information/data, eliminate these legacy systems, and benefit a company by reducing unnecessary licensing and costs.

During this discussion we will explore:

  • Legacy Systems as an Asset or a Liability
  • Data Implication of 'sun setting' applications
  • Techniques for identifying what systems to eliminate
  • Steps to accomplish elimination
  • Tips for justifying to IT and Business Leadership
