Modernize core application codebases without modifying behavior, or maintain your codebase while modernizing infrastructure and data tiers. Reduce cost while adding efficiency efficiency to core application development and support models with Modern Systems' Automated Refactoring services. Automated Refactoring - Mainframe Replatforming "Lift and shift" solution maintains application codebase and modernizes data tier. Use modern workbench tools for development. Instant costsavings and efficiencies without disturbing end users or dev teams. Some organizations wish to reduce costs associated with the mainframe while preserving their legacy application codebase and support model. In these cases, extracting the legacy system from the mainframe and replatforming it in a more cost effective, flexible, modern computing environment is the best option. Automated Refactoring through Replatforming can reduce the system’s total cost of ownership by up to 70% and typically takes between 12 and 18 months to deliver positive ROI. Replatforming also allows you to lift and shift mainframe applications, resources, and data into an open systems environment, preserving your legacy investment. Automated Refactoring - Code Conversion Modernize codebases and data tier without modifying behavior. Offers 100% functionality match for model, view and controller layers. Great for moving apps to Java or C#, and databases to SQL Server, DB2 or Oracle. To reduce costs and to mitigate the growing risks of maintaining systems, many companies opt to rid themselves of mainframes altogether by transforming the legacy application from the old procedural code base, to a modern, object oriented language like Java or C#. This transformation allows for simple integration with other modern systems, much lower cost of operation, and reduced risk associated with the shrinking resource pool capable of maintaining and extending the old codebase. Modern Systems’ application conversion service guarantees an exact functional replica of the legacy application- including all business logic- delivered in maintainable Java or C# code. This service is backed by industry-leading experts and over 30 years of application transformation experience.
