SQL Server Migration to Azure: A Step-by-Step Guide

1. Assessment and Planning

• Identify the source SQL Server version, size, and dependencies.
• Evaluate compatibility using the Data Migration Assistant (DMA).
• Choose a migration destination: Azure SQL Database, Managed Instance, or Azure Virtual Machine.
• Determine downtime tolerance to select an online or offline migration method.

2. Preparation

• Backup data and ensure disaster recovery options are in place.
• Optimize the source database by resolving schema or compatibility issues identified during the assessment.
• Set up the Azure environment, including networking and security configurations.

3. Migration Execution

• Offline Migration:
  • Export database to .bacpac file and import it to Azure SQL Database.
  • Use Azure Database Migration Service for minimal manual intervention.
• Online Migration:
  • Sync data between the source and Azure using the Continuous Data Migration feature.
  • This minimizes downtime for production systems.

4. Post-Migration Validation

• Verify data integrity and functionality using automated testing.
• Address any application adjustments required for Azure compatibility.
• Monitor performance to optimize for Azure’s infrastructure.

5. Optimization and Scaling

• Leverage Azure’s built-in scaling options to adjust database performance.
• Implement cost management practices to optimize expenses.
