Server requirements

Azure Migrate appliance requirements

Azure Migrate and Modernize uses the Azure Migrate appliance for discovery and assessment. You can deploy the appliance as a server in your VMware environment by using a PowerShell script. Learn more about appliance requirements for VMware.

Here are more requirements for the appliance:

• In Azure operated by 21Vianet, you must deploy the appliance by using a script.

• The appliance must be able to access specific URLs in Azure operated by 21Vianet.

Port access requirements

Software inventory requirements

In addition to discovering servers, Azure Migrate: Discovery and assessment can perform software inventory on servers. Software inventory provides the list of applications, roles, and features running on Windows and Linux servers that are discovered by using Azure Migrate and Modernize. It allows you to identify and plan a migration path tailored for your on-premises workloads.

SQL Server instance and database discovery requirements

Software inventory identifies SQL Server instances. The appliance attempts to connect to the respective SQL Server instances through the Windows authentication or SQL Server authentication credentials in the appliance configuration manager by using this information. The appliance can connect to only those SQL Server instances to which it has network line of sight. Software inventory by itself might not need network line of sight.

After the appliance is connected, it gathers configuration and performance data for SQL Server instances and databases. The appliance updates the SQL Server configuration data once every 24 hours and captures the performance data every 30 seconds.

Configure the custom login for SQL Server discovery

Use the following sample scripts to create a login and provision it with the necessary permissions.

Windows authentication

-- Create a login to run the assessment
use master;
DECLARE @SID NVARCHAR(MAX) = N'';
CREATE LOGIN [MYDOMAIN\MYACCOUNT] FROM WINDOWS;
SELECT @SID = N'0x'+CONVERT(NVARCHAR, sid, 2) FROM sys.syslogins where name = 'MYDOMAIN\MYACCOUNT'
IF (ISNULL(@SID,'') != '')
  PRINT N'Created login [MYDOMAIN\MYACCOUNT] with SID = ' + @SID
ELSE
  PRINT N'Login creation failed'
GO    

-- Create user in every database other than tempdb, model, and secondary AG databases (with connection_type = ALL) and provide minimal read-only permissions.
USE master;
EXECUTE sp_MSforeachdb '
  USE [?];
  IF (''?'' NOT IN (''tempdb'',''model''))
  BEGIN
    DECLARE @is_secondary_replica BIT = 0;
    IF CAST(PARSENAME(CAST(SERVERPROPERTY(''ProductVersion'') AS VARCHAR), 4) AS INT) >= 11
    BEGIN
      DECLARE @innersql NVARCHAR(MAX);
      SET @innersql = N''

SQL Server authentication

DECLARE @SID NVARCHAR(MAX) = N'';

Web apps discovery requirements

Software inventory identifies the web server role existing on discovered servers. If a server has a web server installed, Azure Migrate and Modernize discovers web apps on the server.

You can add both domain and nondomain credentials on the appliance. Ensure that the account used has local admin privileges on source servers. Azure Migrate and Modernize automatically maps credentials to the respective servers, so you don't have to map them manually. Most importantly, these credentials are never sent to Azure and remain on the appliance running in the source environment.

After the appliance is connected, it gathers configuration data for ASP.NET web apps(IIS web server) and Java web apps(Tomcat servers). Web apps configuration data is updated once every 24 hours.

Dependency analysis requirements (agentless)

Dependency analysis helps you analyze the dependencies between the discovered servers. You can easily visualize dependencies with a map view in an Azure Migrate project. You can use dependencies to group related servers for migration to Azure. The following table summarizes the requirements for setting up agentless dependency analysis.
