Legacy applications are those which are outdated computer applications. Simply put, these applications were built for older computing environments and while they might still be functional, they don't allow the companies to exploit the advancements of the computing industry. These legacy applications should be upgraded so that more functionalities can be added to them. Let's take a deeper look.
Suppose the application was build when 16 bit computers were in use. So the application carries 16 bit architecture. However, at present, we have 32 bit and 64 bit architectures. It is known that the architecture of the computing environment, or the operating system, must match the applications to enable the application to run inside it. So, basically, a 16 bit application can't be run when using a 32 bit or 64 bit operating system.
Now, there are two options left for the company. Firstly, it can continue to use the 16 bit operating system so that the application can run. Secondly, it can upgrade the application into a modern architecture so that the organisation can benefit from using modern and more advanced operating systems.
Now the second option has some great benefits. Firstly, the company can use the modern OS and other applications to be more productive. Secondly, as the modern operating systems receive security feedback and updates, the organisation is safer as well. Finally, the transformation doesn't lead to loss of data but newer functionalities can be added to the existing legacy application during the upgrade process.
