Why each option
Rehosting, also called lift and shift, moves workloads to the cloud without modifying the application code or architecture.
Rehosting is the migration strategy where an application is moved to the cloud exactly as it exists on-premises, with no changes to code or architecture. This approach prioritizes migration speed and minimal disruption to existing systems. It is the correct term when the requirement explicitly excludes any application modification.
Reimagining involves completely rethinking and redesigning an application to leverage cloud-native capabilities, which requires significant architectural changes.
Replatforming involves making select optimizations to take advantage of cloud services without a full redesign, meaning some changes are applied.
Refactoring involves modifying or rewriting application code to improve structure or adopt cloud-native features, which requires code-level changes.
