EBOOK
Migrating Qt5 to Qt6
Qt 5 has reached its end of life. That means no new features, no long-term bug fixes and no guarantee that your application will keep pace with modern operating systems.
If you want your product to stay relevant, secure and easier to maintain, a move to Qt 6 becomes more than an upgrade: it becomes a strategic safeguard.
Our ebook helps you understand what changes, what breaks and what improves when you migrate, giving you confidence to plan your own transition.
Build future-ready Qt platforms
Qt 6 offers a more robust, modern development environment, with improved modules, better performance and native support for the latest versions of iOS and Android. You can build the same features you rely on today, but faster, more cleanly and with longer support ahead of you.
Key advantages include:
- Extended platform compatibility for current and upcoming mobile systems
- Expanded and improved APIs that simplify maintenance
- Performance gains across the framework
- A strengthened QML toolset, including a dedicated compiler and faster rendering
These improvements translate directly into smoother UI workflows, more responsive applications and simpler C++ integration.
What’s inside
This guide explains:
- How the end-of-life of Qt5 affects security, stability and future development
- Where Qt6 introduces performance and API gains
- How QML evolves, and how that impacts your architecture
- Practical steps to prepare, test and execute a safe migration
- Common challenges development teams encounter and how to avoid them
You’ll get clear recommendations, example scenarios and advice based on real engineering practice.
