PRESS RELEASE FOR IMMEDIATE RELEASE

CGI joins Microsoft migration alliance

Toronto, Ontario, September 28, 2004 – CGI Group Inc. has entered into an alliance agreement with Microsoft Corporation, to assist new and existing clients migrate key business applications away from costly legacy and proprietary host-based mainframe systems. The “Microsoft Mainframe Alliance” has been formed to facilitate moving these clients to more modern Intel architecture and Windows Server Systems platform.

CGI has joined Microsoft in this initiative seeking to provide clients with solutions that will preserve their investment in key business applications and at the same time reduce operating costs and facilitate integration to new web based technologies.

The “Open Data Centre” initiative will utilize CGI’s proven tools and methodologies to port client mainframe applications to the Wintel platform. CGI will also offer this solution as a managed service.

“The natural evolution of technology has lead to the feasibility of migrating customer workloads that were previously best suited to be hosted in a mainframe environment to lower cost, commodity based platforms with minimal reworking of the original application, said Ross Button, vice president, emerging technologies for CGI. “We recognized this evolution and have taken steps with IT industry partners to better assist their customers to assess and, if appropriate, undertake Mainframe Migration initiatives.”

“CGI is one of our key enterprise partners in this alliance,” said Spyros Sakellariadis, mainframe migration initiative project manager for Microsoft Corp. “As a seasoned integrator with .NET experience, CGI delivers real results to their customers, helping them extract maximum value from current IT assets while also taking advantage of the more cost-effective Windows solutions.”

The benefits to new and existing CGI clients will include:

    reducing the total cost of ownership (TCO) by porting applications to modern platforms that offer significantly lower hardware maintenance and software licensing costs;
    moving the application to open technologies that will provide a more efficient development environment for future application enhancement as well as the introduction of web services,
    enabling the client to eliminate business and licensing models that do not keep up with today’s migration options and;
    proactively addressing critical staffing issues such as the declining number of professionals with proficient mainframe skills, the limited number of training programs to teach these skills and, as a result, the added cost burden organizations bear to conduct mainframe training in house.
