Mainframe and AS400 Modernization at Speed and Scale
Present times demand enterprises to operate and scale at a revolutionary pace. This means driving innovation, as well as harnessing the power of the cloud to create a robust foundation for end-to-end digital transformations. However, most of these enterprises, still possess old, monolithic, and expensive mainframe and AS400 workloads to support their legacy systems, which hinders the enterprise’s dreams of becoming a fully digital organization.
Over the years, LTIMindtree has gained a vast amount of experience in legacy applications and hardware, helping large enterprise customers set up and manage the score of such systems. As part of our engagements in the last decade, we built best-in-class solutions, frameworks, and tools to help our customers expedite their journey exiting these legacy systems. Additionally, with our deep domain and business expertise, compounded with technology insights, we help our customers determine the right migration strategy, operating model, and roadmap and integrate with the right partner ecosystem, to exit the legacy landscape to AWS.
LTIMindtree leverages its legacy migration and modernization approach to scale, accelerate and standardize mainframe and AS400 workload migration, as well as application transformation undertakings through a predefined, repeatable, and iterative process. Our comprehensive migration approach brings together industrialized capabilities with exclusive pre-configured industry-specific tools, methodologies, and automation processes across all legacy transformation projects on AWS.
