Desktop software is a wonderful thing. It can do many things that web apps can’t and it provides a more powerful experience for many users. But it has a major problem: it’s not as easy to use on mobile devices and it doesn’t work in a browser.

Nowadays, many people rely on their browsers as their primary way of accessing the web. The legacy system migration process can be a challenge. Moving a legacy system to a web-based system is difficult and not without its risks.

In this guide, we’ll discuss the legacy system migration from desktop to web.

To identify trouble areas, you must assess your system's existing status and behavior. By this approach, you'll know which bugs you'll need to address before, during, and after the transfer. Give close care to any possible data storage and privacy measures.

  • Devise a strategy

You can migrate all the data at once by replacing the old system with a new one. You can also move the system bit by bit in fragments. This is specified with different stages.

Migration can be easily done with apps such as WebSwing that lets you run your legacy swing app within minutes. It also helps you with the step-by-step migration of applications.

  • Identify potential regions for legacy modernization

Some of the components of the desktop system can be migrated and checked whether they need any up-gradation. Instead of migrating and upgrading the whole system, it is better to save costs by upgrading the required components.

  • Optimize things along the way

If the legacy system is complicated, it will be difficult to migrate the data. Migration is a long process that transfers all the data. Therefore, it is better to make some changes to optimize the system for smooth transfer of the system.

There are different migration and modernization techniques that are common for transferring data such as encapsulation, codebase transformation, and building custom web applications.

  • Encapsulation

This means condensing a current desktop program into a web service that is more user appealing. This is the fastest and most crucial way to web-based modernization. The application should be in a good state and has the ability to update.

  • Custom web application

The app’s appearance and style can be redefined by creating a prototype of the web app. New opportunities that cloud solutions will provide can be assessed. It also has the benefit of using the latest technology to create web apps.

The codes of the legacy system are converted into a manner that is appropriate for a web application. The tools present can simplify and speed up the process. This can be successful if the codes are placed together properly.


Migration of legacy systems is a complex, tough procedure. Nevertheless, this is necessary for many enterprises, which seek to ramp up business expansion, increase flexibility, level of service, save expenses, and give their consumers and associates up-to-date services.
