Explanation:
You should identify the following migration steps in order:
1. Assess
2. Deploy
3. Release
The Microsoft Adoption Framework for Cloud provides you with guidelines to construct a plan for your journey into the cloud. The Microsoft Cloud Adoption Framework envisages the following main methodologies: Define strategy, Plan, Ready, Migrate, and Innovate.
First, during the assessment step of the Migrate methodology, you should assess your workloads in terms of calculating the migration costs and determining the required modernization effort and deployment tools.
Next, you should deploy your workloads by moving them, either without modernizing (lift-and- shift) or modernized, into the cloud.
Finally, you should test, optimize, and document your migrated workloads and, if the result is as expected, then you can release the workloads to your users. During this phase you should hand over workloads and documentation to your operation, security, and governance teams.
You should not identify Plan as one of the Migration steps. According to the Microsoft Adoption Framework for Cloud, during the Plan step you assess your digital estate (which workloads you can move as they are, which have to be modernized or rebuilt, which workloads you do not need anymore), align it with the business outcomes, evaluate skill gaps, and plan for adoption & change management. As such, the Plan step has to be carried out before you start your migration.
You should not identify Ready as one of the Migration steps. According to the Microsoft Adoption Framework for Cloud, during the Ready step you need to create your target environment, called the landing zone. As soon as your landing zone is in place, you are ready to start migration.
