IT organizations facing business pressure to reduce spending tend to prioritize replatforming their mainframes to the cloud. However, replatforming does not eliminate programming language obsolescence, requiring companies to retain obsolete software engineering processes to develop and maintain outdated applications. More advanced methods include the rewrite or reengineering of legacy applications to Java, .NET or C# to introduce DevOps and agile development methods.
Application rewrite tools automate the generation of maintainable application code integrated with modern application development environments. Application reengineering automation uses reverse-engineering techniques to analyze and explain the legacy code, map data and application dependencies, and expose business rules for human reviews. Application reengineering allows companies to eliminate dead code and technical debt, as well as update the business rules before automatically generating new code using GenAI and code assistant tools.
