Our software re-engineering services assist our clients in converting their existing IT systems to newer technologies and platforms developed by third-party vendors. Our re-engineering services include web-enabling our clients existing legacy systems, database migration, implementing product upgrades, and platform migrations, such as mainframe to client-server and client-server to Internet platforms.
As an example, a client in the computer manufacturing industry had a large, disparate installed base of legacy systems which needed to be re-engineered to work with open systems with newer technologies. Our team of over 150 professionals re-engineered a suite of applications from several legacy systems such as VAX/VMS, AS/400 and IBM mainframes, running on Ingres, Sybase and DB2 databases, to new generation systems such as RS6000/AIX, running on Oracle database and Holos OLAP tools. Our solution provides a unified, enterprise-wide platform for over 50 applications for 10,000 users spread across North America, Europe and Asia, and we now have been engaged by this client to perform its follow-up application maintenance function, a function previously performed in-house by the client.
