Zorluk: OrtaMigration Assessment and Strategy

An investment firm plans to migrate a legacy portfolio management system from an on-premises VMware vSphere environment to Azure. The system consists of three web servers and a Microsoft SQL Server database server that hosts multiple databases with active cross-database queries. You need to design a migration assessment strategy that identifies all application dependencies and evaluates database compatibility with Azure. Which two actions should you include in the assessment strategy? (Choose two.)

  1. Deploy the Azure Migrate appliance to perform agentless dependency analysis on the virtual machines.Cevap
  2. Assess the database compatibility for Azure SQL Managed Instance by using the Azure Migrate: Discovery and assessment tool.Cevap
  3. C
    Target Azure SQL Database elastic pools as the migration destination for all databases.
  4. D
    Configure Active Directory Federation Services (AD FS) to synchronize user identities before performing the migration assessment.
  5. E
    Schedule the migration of the web servers to Azure before performing any dependency analysis on the backend database.

Cevap

To perform a successful migration assessment, you should deploy the Azure Migrate appliance to perform agentless dependency analysis on the virtual machines, and assess the database compatibility for Azure SQL Managed Instance by using the Azure Migrate: Discovery and assessment tool.
The correct actions are deploying the Azure Migrate appliance for agentless dependency analysis and performing a database assessment targeting Azure SQL Managed Instance. Agentless dependency analysis helps map all connections between the web servers and database without guest agent overhead, which is critical for planning migration waves. Selecting Azure SQL Managed Instance for assessment is correct because the database uses cross-database queries, which is a feature not supported by Azure SQL Database single databases or elastic pools.

Adım Adım Çözüm

1
Analyze application dependencies to identify workload boundaries.
Identify all communication paths and group the web servers with the SQL Server.
This ensures that no dependent systems are left behind or experience high latency due to split-workload states.
2
Analyze database requirements to select the correct migration destination.
Identify cross-database query usage on the SQL Server.
Cross-database queries are not supported in Azure SQL Database single database/elastic pools, requiring Azure SQL Managed Instance.
3
Run a database-specific assessment using Azure Migrate.
Verify compatibility and identify any potential migration blockers or remediation steps for Azure SQL Managed Instance.
An assessment provides SQL Server-specific migration recommendations and readiness status.
