AZ-305 · Question 51 · Domain 4.3: Design Migrations
Your company is migrating a portfolio of applications to Azure.
One specific application is a monolithic ASP.NET web app running on Windows Server 2008. The development team wants to move it to Azure App Service to reduce operational overhead. They will use the Azure App Service Migration Assistant to package the app and deploy it to Azure without changing the application's source code.
Which migration strategy (from the 7 R's) does this represent?

D.
Repurchase
How to approach this question
Moving from IaaS (VM) to PaaS (App Service) without changing code is the definition of Replatforming.
Full Answer
B.Replatform✓ Correct
Replatform
This scenario describes 'Replatforming'. The application code remains largely unchanged, but the underlying infrastructure is upgraded from a traditional Virtual Machine (IaaS) to a fully managed Platform as a Service (PaaS) offering like Azure App Service. This provides cloud benefits (auto-scaling, no OS patching) without the cost of a full code rewrite.
Common mistakes
Confusing Replatform with Refactor. Refactoring requires code changes. Replatforming just changes where the code runs (IaaS to PaaS).
