Legacy application documentation

Gaining the full value of your legacy systems

One of the key challenges of maintaining legacy applications is a lack of supporting documentation and subject matter expertise. Over time, the original business purpose and workflows of old systems can be forgotten due to staff turnover, interfering with ongoing maintenance and improvements, creating project, operational, audit and retention risks, and increasing the workload of current staff.

CGI offers a Legacy Application Documentation (LAD) service designed to develop technical and architecture documentation for any type of legacy system. Using our proprietary LAD tools and processes, our experts can define and document the workflows of an application in the absence of available subject matter experts and provide recommendations in terms of maintenance, rationalization and migration.
