Legacy applications provide business-critical functions within the enterprise application landscape but incur large operations and maintenance costs. Additionally, they pose a number of challenges including unsupported hardware and software, inflexible and closed architectures, lack of integration, and limited technical resources.

Your systems should be aligned, reliable and compatible, while cutting down on excess work and overlapping processes that slow you down.
