• Minimum changes needed are applied to operate in target cloud environment.
• Suitable if environment and workloads are similar or little or no business need for change.
• It requires the least time and is the quickest migration

Improve and move:

• It involves changing the workloads or operation to benefit from cloud-native capability
• Improvement in performance/ features/ cost/ user experience is realized
• Suitable if a major update was to be done on the workload

Rip and replace:

• Suitable if existing is not to be maintained or change in requirements or no support in GCP
