With the push to the cloud accelerating, it’s critical to understand how to migrate on-prem servers to Microsoft Azure. As an IT professional, you are likely to encounter situations where you need to plan and execute such migrations.

In this course, you will learn how to evaluate migration scenarios by using Azure Migrate. We’ll cover the discovery and assessment of on-prem VMware environments and how to identify workloads that can and cannot be deployed.  You’ll also learn about Azure Migrate port requirements and how to determine if the target environment is supported for a migration.

Later in the course, you will learn how to deploy and configure Azure Site Recovery (ASR) and how to use it to migrate an on-prem server to Microsoft Azure. You’ll also learn how to configure storage, create a backup vault, and how to prepare the source and target environments ahead of a migration.

The topics covered in this Azure course map very closely to learning objectives covered in the Microsoft Azure certification exams.  By mastering the topics covered in this course, the student not only learns skills necessary for assessing environments for migration suitability and for performing those migrations, but the student also learns skills necessary to prepare for certification exams.

  • General knowledge of IT infrastructure
  • General knowledge of the Azure environment


The next step in the process is to verify VMs in the portal. Discovery time will depend on how many VMs are being discovered. To begin open the migration project and then click machines. This is shown under the Manage section. Ensure that the VMs you want to discover appear in the portal. As you can see in the server list here all machines show requires configuration in the dependencies column. This is because dependency visualization of these machines requires a deeper discovery of them. This involves installation and configuration of additional agents on the on-prem machines. These agents include the Microsoft Monitoring Agent and the Dependency Agent. Using dependency visualization allows you to view network dependencies of grouped machines and to identify related machines that need to be migrated together to Microsoft Azure. Since we're not migrating dependent machines, these agents are not required. 

As such, there's no need to install them. So let's continue with the assessment creation by clicking Create assessment. Click View all to review the assessment properties. As you can see there are numerous options that can be configured when creating an assessment. The options under TARGET DETAILS are used to specify a region, along with the required pricing tier and storage type. Also included in the TARGET DETAILS is the option to specify reserved instances. The SIZING section offers the ability to specify sizing criterion and a performance history to use for sizing. Percentile utilization allows you to further fine-tune sizing requirements. The VM series option allows you to specify which VM sizes should be considered when making recommendations. 

And the comfort factor allows you to adjust for usage spikes. The pricing section offers various pricing options to consider when making recommendations. After making your selections click save and then create a group and specify a name for it. Choose the machines that you want to add to the group and then click Create assessment to create the group and the assessment. After creating the assessment, view it by clicking Overview. From the overview page you can click on the actual assessment. Key metrics are displayed. These metrics include Azure readiness, compute costs, and storage costs. 

These statistics are all based on the configured settings of the assessment along with the discovered information for the on-prem VMs. This information allows you to review what the Azure environment will look like from a sizing perspective, along with associated costs following a perspective migration. The assessment can be exported and downloaded as an Excel file by clicking Export assessment. As you can see, performing an assessment prior to a migration offers insight into the current on-prem VMware environment and provides important feedback that can be used to run a smoother migration through Microsoft Azure.
