Legacy Systems

ITD supports COBOL, CICS, and NATURAL systems that run on a mainframe computer. These are customized applications that were written by ITD or purchased from vendors. While it is not ITD's direction to write or to procure new legacy applications, many of these systems serve the customers well, and cost/benefits do not justify replacement at this time.

ITD works with our customers to analyse and suggest replacement of these systems as needed. It is expected that 90% of today's legacy systems will be replaced by 2010.
