Your team plans to move a legacy web application to Google Cloud. They intend to make only minor configuration changes and will replace the on-premises database with Cloud SQL, but the application code itself will stay the same. Which migration approach does this scenario best represent?
The described scenario involves small, infrastructure-level changes-such as swapping a self-managed database for Cloud SQL-while leaving the application code largely untouched. This aligns with a replatform, or "move and improve," strategy. Rehost (lift and shift) would copy the workload exactly as it is, with no component substitutions. Refactor requires significant code changes to take full advantage of cloud-native capabilities. Retain means keeping the workload in its current environment and not moving it at all.
