Question details
The user needs to move a database between Azure Database for MySQL Flexible Server 8.0 instances.
- Product
- Azure Database for MySQL Flexible Server
- Device & OS
- not provided
- Scenario
- Migrating a database from a source server with public access to a destination server using VNet integration, with no virtual machines available for intermediate routing.
- Observed behavior
- Seeking the appropriate method, network configuration steps, or built-in Azure tools to facilitate this specific cross-network database migration.
Before attempting the migration, ensure you have appropriate administrative access to both the source and destination Azure Database instances, and verify the Azure networking rules for your VNet integration.
Consult Microsoft Q&A for Complex Azure Database Migration Guidance
Because migrating between instances with differing network configurations (public access to VNet) without VMs involves advanced Azure infrastructure, contacting specialized cloud support is highly recommended.
Network-specific migrations often fall outside standard community support. Azure's official Q&A platform connects you directly with Microsoft cloud engineers who can provide secure, built-in tool recommendations tailored to your infrastructure.
Open your web browser and navigate to the official Microsoft Q&A platform, specifically the 'Azure Database for MySQL' section.
Click 'Ask a question' and detail your configuration: state that your source server uses public access, the destination uses VNet integration, and that no virtual machines are available.
Ensure your post is tagged with 'Azure Database for MySQL' and 'Azure SQL Database' to reach the correct technical specialists.
Document Your Database Migration Strategy with WPS Office
While WPS Office cannot migrate an Azure database, it is the perfect free, lightweight solution for planning your migration, charting database architectures, and drafting server configuration documents. Highly compatible with Microsoft Office formats, it provides a familiar UI for seamless document management.
Frequently Asked Questions
Can I use Azure Database Migration Service for MySQL Flexible Server?
Yes, Azure provides the Database Migration Service (DMS) which supports migrating from various sources to Azure Database for MySQL. You will need to configure network routing correctly so DMS can access both the public source and the VNet-integrated destination.
How do I migrate MySQL databases without an intermediate virtual machine?
You can utilize managed services like Azure Data Factory or Azure Database Migration Service. These operate as Platform-as-a-Service (PaaS) offerings and do not require you to manually provision or manage dedicated virtual machines to execute the data transfer.
Is there downtime associated with moving to a VNet integrated MySQL server?
Downtime depends strictly on the migration method chosen. Offline migrations (like exporting and importing dumps) require downtime, while online migration tools sync changes continuously, minimizing your cutover downtime.
