On top of that, they provide coaching and training for your team so that after the migration, you’re not left scratching your heads.

Conclusion
When you look at application modernization in Europe, one thing’s clear – there’s no single way to do it. Different companies take very different approaches depending on what tech they know best, the size of the client, and what the project really needs. Some lean heavily on automated migration tools and cloud moves, while others dive into refactoring and redesign to make systems easier to maintain and scale. What they all share, though, is a commitment to helping businesses get legacy systems working for today without breaking what already works.
Picking the right partner is really about finding the right fit. Maybe speed and cost matter most to you, or maybe you need someone who really knows a specific platform or understands strict compliance rules. Either way, Europe’s market has a solid mix of options. The main thing to remember is that modernization isn’t just about slapping new tech on old systems – it’s about making them smarter, smoother, and more practical for what your business actually needs right now.
