Examples of Popular Legacy Technologies Leveraging Modernization

Businesses utilizing SAP have customized the fundamental application to align with their particular requirements. However, these adaptations can be expensive and present challenges when updates are needed for future needs. This is where the modernization of legacy applications comes into play, offering a solution to these challenges. Companies seized an opportunity to unlock new value by opting for low-code application development to modernize SAP’s legacy technology. Through this approach, they enhanced and refined the system with the latest capabilities, ensuring its competitiveness in the ever-evolving landscape.

Another example is .NET and Oracle. Developers construct enterprise systems with these technologies. They’re chosen because of their ability to provide the exact features needed, surpassing Commercial Off-The-Shelf (COTS) solutions. Yet, when it comes to later upgrades with new features and capabilities, these legacy systems can become a real headache in terms of complexity. Legacy application improvement emerges as a proven solution to the challenge. Many organizations have revamped and optimized their .NET and Oracle-built legacy tech with a low-code approach. It allows them to keep and upgrade the original technology with modern capabilities, offering a win-win solution.
