CV0-004 Practice Question: Planning to migrate a legacy application to the…
A company is planning to migrate a legacy application to the cloud. They want to leverage cloud-native features while minimizing code changes. Which TWO migration strategies should they consider?
⚠ Common exam trap
CompTIA often tests the distinction between 'Replatform' and 'Refactor,' where candidates mistakenly choose Refactor thinking it allows minimal changes, but Refactor actually requires significant code rework to adopt cloud-native patterns like containerization or serverless.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Replatform
Replatform (A) is correct because it involves migrating the application to a cloud-managed platform (e.g., moving from a self-managed database to Amazon RDS or Azure SQL Database) with minimal code changes, allowing the company to leverage cloud-native features like automated backups and scaling. Replace (D) is correct because it means adopting a SaaS alternative (e.g., replacing a custom CRM with Salesforce) that provides cloud-native capabilities without modifying existing code, aligning with the goal of minimizing code changes.
