Q1
Do users notice the migration?
No. Traffic is routed slice by slice, so users simply get faster pages over time.
Q2
Do we need to freeze new features?
No. New features are built directly on the modern stack while old ones migrate.
Q3
Can you also move it to the cloud?
Yes. Once on modern .NET the app runs in containers, so moving to Azure or AWS is straightforward.
