Migrating and modernizing applications

7/16/2025 Angular AngularJS Migration Modernization Upgrade Improve

Is your application also in need of an upgrade, but is the execution quickly falling behind because, for example, your own development team is too busy working on important new features? Outsource your desired or perhaps urgently needed migration or update and involve us in your project! A real-world example.

For one of our clients, we are working on converting an outdated AngularJS application to the latest version of the modern Angular framework. Prior to this, we mapped out for our client the most efficient and cost-effective path to take. Within six months, the application's codebase will be migrated to Angular 19, while we simultaneously implement various optimizations to create a renewed platform that is modern, highly scalable, and easily maintainable. What does such a process look like?

  • We analyze the current application and determine the best approach for the conversion. This could mean gradually rebuilding the application or starting a new project from scratch, using the old application as a reference.
  • The conversion is divided into deliverable milestones, each resulting in a part of the application running on a modern framework, utilizing the latest techniques enabled by it.
  • Code is optimized immediately, regardless of the state in which it was provided to us. This includes implementing best practices and current industry standards, adding clear annotations within the source code (such as code summaries), technical documentation, and everything needed to make your codebase pleasant to work with again.
  • At each delivery, we review the past milestone with the client and, if necessary, provide an explanation of the changes made. We can also ensure proper knowledge transfer to the client’s own development team if they have not yet worked with the newly applied techniques.

In this specific case, we are dealing with a migration from a years-old AngularJS project to the latest Angular. This is a conversion that spans 19+ versions and also involves a shift between two different frameworks. Despite the similar naming, AngularJS and Angular are distinct frameworks, and the transition goes beyond simply adopting TypeScript instead of pure JavaScript. However, we can also perform migrations to and from other stacks, such as C# and/or Blazor, React, VBA, and more.
