    Select modernization approach

    Implementation is where actual coding takes place according to product specifications. Our engineers choose suitable programming languages and frameworks and decide whether your desktop app needs modularity or a plugin system. Based on the chosen tech stack, our team picks software development strategy and methodology and creates a detailed roadmap for every implementation stage.

  • 04

    Begin the modernization process

    The application modernization process involves implementing your chosen approach, which ranges from rewriting code to migrating data. Depending on the size and complexity of your legacy app, the process starts with the discovery phase or moves straight to modernization.

  • 05

    Test and deploy new application

    After completing the modernization process, we thoroughly test your new application before an official launch. This ensures everything works as intended, and users won’t encounter glitches once it’s live.

  • How do you modernize an application?

    We strategically plan our software product modernization services, tailoring them to suit your needs and goals. Our first step is to assess the current technology stack and architecture of your application. We identify outdated components, legacy code, and potential security vulnerabilities.

  • Why is application modernization important?

    Application modernization is essential for you to maintain competitiveness and relevance in the fast-paced technological landscape. By software modernization, companies enhance their user experience, adapt to changing business needs, improve efficiency, and boost productivity. Modernized applications also offer better security, compliance, and scalability while reducing operational costs.

  • What are the business risks of not modernizing a legacy app?

    Neglecting to modernize a legacy app exposes your business to significant risks. Some of them include heightened security vulnerabilities, inefficient operations, poor user experience, limited scalability, higher maintenance costs, compliance issues, and integration challenges.

  • Do I need to provide detailed functional specifications for a successful app modernization process?

    It’s great if you have documentation at hand – we will move faster with your project. If not, our experts will handle app modernization even in the absence of extensive documentation. We proactively mine the essential business logic from your existing app and perform a thorough investigation of code dependencies and component integrations. Additionally, we foster seamless collaboration with your in-house IT team, third-party vendors, and other knowledgeable parties to ensure a streamlined modernization process.

  • Is it possible to prevent operational downtime during application modernization?

    Absolutely. We adopt a strategic approach to cloud application modernization services, ensuring uninterrupted uptime for your apps. We divide applications into several independent parts, introducing changes incrementally. This phased deployment minimizes disruptions so that your app remains available and fully functional throughout the modernization process.
