Comprehensive migration source support
The migration service supports diverse source environments including on-premises PostgreSQL deployments, Azure Virtual Machines, Amazon RDS and Aurora instances, and Google Cloud SQL databases. This broad compatibility ensures that organizations can transition from multiple cloud providers and on-premises systems to Microsoft Azure with consistent reliability.
Continuous synchronization and minimal disruption
Available through both the Azure Portal and Azure CLI, the online migration feature maintains continuous data synchronization between source and target servers. This continuous sync approach allows businesses to keep applications operational while data transfers occur transparently in the background, significantly reducing service interruptions during the migration process.
Streamlined cutover process
When synchronization reaches zero latency, administrators can perform the final cutover to shift all connections to the new environment. Microsoft recommends stopping all write operations on the source system before cutover and thoroughly validating the migrated data to ensure integrity.
Production workload optimization
According to Microsoft documentation, online migration is specifically designed for production workloads requiring high availability and minimal downtime. Meanwhile, offline migration remains the preferred option for smaller databases or testing scenarios where brief service interruptions are acceptable.
Enhanced automation and risk reduction
By leveraging Azure’s built-in replication and automation tools, enterprises can accelerate migration timelines while maintaining business continuity. The automated approach substantially minimizes manual intervention, helping teams mitigate risks associated with complex data transitions. Microsoft’s technical community notes this new experience delivers smoother transitions for mission-critical workloads compared to previous migration tools.
Connection management best practices
Following successful migration verification, administrators should update all application connection strings to point toward the new Flexible Server instance. This crucial step ensures that applications seamlessly connect to the migrated database environment without service disruption.
