CCSP Practice Question: During a cloud migration, a company decides to…
During a cloud migration, a company decides to move a legacy application with no code changes. Which migration strategy are they using?
⚠ Common exam trap
It's easy for candidates to confuse rehost with replatform; candidates might think any migration without code changes is replatform, but replatform involves some modifications (e.g., changing OS or database).

Correct answer & explanation
✓
Rehost (lift and shift)
Rehost (lift and shift) means moving an application to the cloud without modifying its code or architecture. Since the company is migrating a legacy application with no code changes, this is the definition of a rehost strategy. The other strategies involve varying degrees of modification or replacement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Refactor
Why it's wrong here
Refactoring means re-architecting or rewriting application code to exploit cloud-native features, which contradicts moving with no code changes. It is tempting because refactoring delivers the greatest long-term cloud benefit, and would be correct where the business accepts code modification to gain scalability or resilience.
- ✗
Repurchase
Why it's wrong here
Repurchase means replacing the existing application with a different product, typically SaaS, so the legacy code is abandoned rather than migrated unchanged. It is tempting because it eliminates maintenance of ageing software, and would be correct where a commercial SaaS alternative meets the functional requirements.
- ✗
Replatform
Why it's wrong here
Replatform involves making limited modifications, such as swapping a database engine or adjusting configuration, so code is not left untouched. It is tempting because it captures some cloud benefits with modest effort, and would be correct where minor tuning is acceptable to gain managed services.
- ✓
Rehost (lift and shift)
Why this is correct
Rehosting redeploys the legacy application onto cloud infrastructure without modifying its code, directly satisfying the no-code-changes constraint. Unlike refactoring or replatforming, which require code or configuration alterations, lift and shift preserves the existing artefact, making it the fastest migration path.
