Common questions
What is application modernization?
Application modernization is upgrading legacy software, old .NET Framework apps, monoliths, or on-prem systems, to modern, cloud-native architectures without losing the business logic that already works. It spans replatforming, refactoring, re-architecting, and the data migration that comes with them.
How do you modernize without a risky big-bang rewrite?
We use the strangler-fig pattern: stand up the new system beside the old one and move functionality across in small, reversible slices. The legacy app keeps serving users the whole time, so there is no flag-day cutover and no quarter-long freeze.
Can you migrate .NET Framework to modern .NET?
Yes, it is one of our core paths. We move .NET Framework workloads to current cross-platform .NET, untangle the dependencies that block the upgrade, and replatform onto managed cloud services, including AWS GovCloud or Azure Government for regulated workloads.
Will modernization break what already works?
No. We characterize current behavior with tests first, migrate in slices behind feature flags, and keep a rollback path at every step. The goal is a system that is cheaper and safer to run, not a rewrite that trades old problems for new ones.
