Modernizing Legacy Apps: Tips to Overcome Key Challenges

Business dynamics keep changing and organizations that rely on legacy applications must adopt consumer behavior to embrace efficient models that enable competence. As technologies that the world relies on continue to evolve at a mind-boggling pace, there has been a growing focus on legacy applications as well as the modernization of such apps. While they may have served businesses for decades, legacy apps prove to be a liability currently. The solution, then, is application modernization.

It refers to a digital transformation strategy to re-purpose existing software while making it compatible with modern devices and applications. The applications enable rebuilding them by rewriting the source code, augmenting the application, or plugging the existing code and dependencies into a modern platform.

Though before you dive into the process, it is important to be aware of the challenges associated with the process as well:


One of the biggest challenges facing companies when it comes to app modernization is the cost associated with the process. This issue is further compounded when one realizes that getting a precise estimate of the cost associated with modernization can prove to be yet another challenge. The most effective way to address this problem is by organizing the app into components and then deciding which of these components is worth investing in and discarding the rest.

Quality Assurance

When a company has been using its legacy apps successfully and largely without any issues, it is obvious that the company would expect the same levels of quality from the modernized app. The key to addressing this concern is to make sure that you pick the service provider carefully. This is because not all service providers will offer dedicated QA teams that will use industry best practices to deliver the best possible results.

Data Migration

A legacy system has an abundance of data in various formats, and different locations & all of this data must be migrated too, of course. It can seem to be a challenging task at the outset but rest assured that most modern cloud service providers with advanced plug-ins and solutions are specifically meant to facilitate data migration.

On-Premise and Cloud Infrastructure Integration

A lot of times, companies opt to not completely abandon their systems and software based on on-premise infrastructure. There are various reasons a company may choose to opt to retain said systems, but no matter these reasons the fact remains that not migrating these systems on account of fear of inefficiencies, operational silos, etc. can prevent the company from being unable to leverage the full potential of cloud computing. The solution to this challenge is found in modern cloud-computing services themselves; these services offer myriad tools to enable seamless integration of on-premise and cloud infrastructure and provide the company with a 360-degree view of the business.

There is no denying that migrating legacy applications is not a simple task by any measure. Furthermore, as demonstrated via the above discussion, the process of such migration comes with its own set of challenges. Yet, the fact remains that migrating legacy apps is an excellent opportunity that helps companies fortify operations, boost efforts aimed at strategic business goals, and so much more. The migration process is an opportunity for companies to put together new systems that are easy to adapt and fortify myriad processes across a given company’s operations. However, for the process to be able to deliver such value, it is important to be aware of the challenges one is likely to face, such as the ones listed above, and be prepared to quickly resolve them as well. Now, if you are ready to migrate your legacy app to the cloud, we highly recommend you start by looking for a trusted service provider who can assist you throughout the process.
