The framework illustrated in the preceding diagram has four phases:
•Assess. In this phase, you assess your source environment, assess the workloads that you want to migrate to Google Cloud, and assess which VMs support each workload.
•Plan. In this phase, you create the basic infrastructure for Migrate for Compute Engine, such as provisioning the resource hierarchy and setting up network access.
•Deploy. In this phase, you migrate the VMs from the source environment to Compute Engine.
•Optimize. In this phase, you begin to take advantage of the cloud technologies and capabilities.
