    Frequently Asked Questions

    Among the main reasons to migrate to .NET Core are modern modular architecture that enables seamless maintenance and scalability; the ability to speed up time-to-market thanks to faster release cycles; long-term flexibility to choose tech stack; perfect integration with modern APIs and external systems; and lower costs for maintenance and upgrades.

    Sure. In contrast to .NET Framework, which is limited by Windows-only performance, .NET Core provides the opportunity to run natively in different environments, such as Windows, Linux, macOS, and the cloud. Once migrated, your system will be fully compatible, so you can reduce duplications and complexity, as well as provide an excellent user experience everywhere.

    One of the key reasons to migrate .NET Framework to .NET Core, is the ability to deliver new features faster and with minimized risks, regardless of environment. That’s why adoption of CI/CD pipelines is an inevitable part of modernization. We take care of the entire process, so containerization (Docker/Kubernetes) and automated provisioning are included as well.

    Yes. When you migrate to .NET Core you’ll get the opportunity to operate cloud-based and break free from Windows licensing dependencies. Moreover, modular architecture upkeep is significantly simpler and cheaper, so you can optimize your operational budget.

    Absolutely. We do not just convert .NET Framework to .NET Core; we offer ongoing support even after migration. We monitor system performance regularly to provide necessary fixes and improvements. Also, your team will get well-structured documentation and expert training to manage the system independently and confidently.
