This article provides a quick overview of the Azure Migrate service.
15
+
Azure Migrate is a service that helps you decide, plan and execute your migration to Azure. Azure Migrate helps you find the best migration path, assess for Azure readiness and cost of hosting workloads on Azure, and perform the migration with minimal downtime and risk. Azure Migrate provides support for servers, databases, web apps, virtual desktops and large-scale offline migration using databox.

Azure Migrate provides a simplified migration, modernization, and optimization service for Azure. All pre-migration steps such as discovery, assessments, and right-sizing of on-premises resources are included for infrastructure, data, and applications. Azure Migrate’s extensible framework allows for integration of third-party tools, thus expanding the scope of supported use-cases. It provides the following:

19
-
-**Unified migration platform**: A single portal to start, run, and track your migration to Azure.
20
-
-**Range of tools**: A range of tools for assessment and migration. Azure Migrate tools include *Azure Migrate: Discovery and assessment* and *Migration and modernization*. Azure Migrate also integrates with other Azure services and tools, and with independent software vendor (ISV) offerings.
21
-
-**Assessment, migration, and modernization**: In the Azure Migrate hub, you can assess, migrate, and modernize:
22
-
-**Servers, databases and web apps**: Assess on-premises servers including web apps and SQL Server instances and migrate them to Azure.
23
-
-**Databases**: Assess on-premises SQL Server instances and databases to migrate them to an SQL Server on an Azure VM or an Azure SQL Managed Instance or to an Azure SQL Database.
24
-
-**Web applications**: Assess on-premises web applications and migrate them to Azure App Service and Azure Kubernetes Service.
25
-
-**Virtual desktops**: Assess your on-premises virtual desktop infrastructure (VDI) and migrate it to Azure Virtual Desktop.
26
-
-**Data**: Migrate large amounts of data to Azure quickly and cost-effectively using Azure Data Box products.

Azure Migrate provides a simplified migration, modernization, and optimization service for customers who are looking at migrating their on-premises workloads to Azure. This tool provides you with a one stop solution to discover, generate business case, assess, right-size, and eventually migrate your infrastructure, data, and web application workloads. A general migration journey includes the following phases:

The Azure Migrate hub includes these tools:
23
+
-**Decide**: The first step in a migration journey is to identify your workloads. This process of identification is known as discovery. To discover your workloads you can deploy a light-weight [Azure Migrate appliance](https://learn.microsoft.com/azure/migrate/migrate-appliance) (recommended approach) or quickly import the inventory data for your workloads. The Azure Migrate appliance is a virtual appliance that can be deployed on a server on your datacenter. The appliance collects the configuration and performance data for your servers and continually sends it over to Azure Migrate Service. Once the inventory of workloads is identified you can create a business case to make your decision to migrate to Azure.

36
-
**Data Migration Assistant** | Assess SQL Server databases for migration to Azure SQL Database, Azure SQL Managed Instance, or Azure VMs running SQL Server. | Data Migration Assistant is a stand-alone tool to assess SQL Servers. It helps pinpoint potential problems blocking migration. It identifies unsupported features, new features that can benefit you after migration, and the right path for database migration. [Learn more](/sql/dma/dma-overview).
37

25
+
-**Business case** helps you decide if you should migrate your on-premises workloads to Azure, by estimating the costs and savings of moving to Azure. The business case helps you identify-
26
+
- On-premises vs Azure total cost of ownership
27
+
- YoY comparison of cash flows
28
+
- Resource utilization-based insights on Azure targets.
29
+
- Long-term cost reduction by switching from a capital expenditure (Capex) model to an Operating expenditure (Opex) model. Learn more about [business case](https://learn.microsoft.com/azure/migrate/concepts-business-case-calculation).

> If you're in Azure Government, external integrated tools and ISV offerings can't send data to Azure Migrate. You can use tools independently.
31
+
-**Plan**: Once the decision is made to migrate to Azure, the next important phase is planning of migration. To plan migration in detail you can assess your discovered workloads using Azure Migrate assessments to find the readiness, right sized targets, configuration of the target Azure resources, cost of hosting target resources on Azure and migration guidance.
32
+
-**Azure readiness**: Assesses whether on-premises servers, SQL Servers and web apps are ready for migration to Azure.
33
+
-**Right****sizing**: Estimates the size of Azure VMs/Azure SQL configuration/number of Azure VMware Solution nodes after migration.
34
+
-**Azure cost estimation**: Estimates costs for running on-premises servers in Azure.
35
+
-**Dependency Analysis:** Dependency analysis helps you understand the network dependencies between servers in your datacenter so that you can make high confidence migration plans without missing any critical dependency during migration. Learn more about [dependency analysis](https://learn.microsoft.com/azure/migrate/concepts-dependency-visualization).
36
+
37
+
-**Execute**: In this phase, you perform the migration or modernization of your workloads to move to Azure. You can use the Azure Migrate service or third-party tools to migrate your servers, databases, web apps, or virtual desktops with minimal downtime and risk. You can migrate the following workloads using the integrated migration tool.

Azure Migrate integrates with several ISV offerings.
|**On-premises VMware VMs**| Migrate VMs to Azure using agentless or agent-based migration.<br><br>For agentless migration, the Migration and modernization tool uses the same appliance, used for discovery and assessment of servers.<br><br>For agent-based migration, the Migration and modernization tool uses a replication appliance. |
42
+
|**On-premises Hyper-V VMs**| Migrate VMs to Azure.<br><br>The Migration and modernization tool uses provider agents installed on Hyper-V host for the migration. |
43
+
|**On-premises physical servers or servers hosted on other clouds**| You can migrate physical servers to Azure. You can also migrate other virtualized servers, and VMs from other public clouds, by treating them as physical servers for the purpose of migration. The Migration and modernization tool uses a replication appliance for the migration. |
44
+
|**Web apps hosted on Windows OS in a VMware environment**| You can perform agentless migration of ASP.NET web apps at-scale to [Azure App Service](https://azure.microsoft.com/services/app-service/) using Azure Migrate. |

-**Current version**: Use this version to create projects, discover on-premises servers, and orchestrate assessments and migrations. [Learn more](whats-new.md) about what's new in this version.
103
-
-**Previous version**: The previous version of Azure Migrate, also known as classic Azure Migrate, supports only assessment of on-premises servers running on VMware. Classic Azure Migrate is retiring in Feb 2024. After Feb 2024, classic version of Azure Migrate will no longer be supported and the inventory metadata in classic projects will be deleted. You can't upgrade projects or components in the previous version to the new version. You need to [create a new project](create-manage-projects.md), and [add assessment and migration tools](./create-manage-projects.md) to it. Use the tutorials to understand how to use the assessment and migration tools available. If you had a Log Analytics workspace attached to a classic project, you can attach it to a project of current version after you delete the classic project.
