Changing a VPC and Subnet

Scenarios

A Virtual Private Cloud (VPC) is an isolated private virtual network environment provided for cloud databases using network virtualization technologies. A subnet is a unique CIDR block with a range of IP addresses in a VPC. You can change the VPC and subnet of an RDS for SQL Server instance.

Constraints

• You can change a VPC and subnet only through the primary instance. To use this function, submit a service ticket to request required permissions.
• If there are read replicas, changing the VPC and subnet of the primary instance will also change those of the read replicas. The subnet of the read replicas must be the same as that of the primary instance.
• Changing a VPC or subnet will briefly interrupt workloads. Perform this operation during off-peak hours.
• Subnets in a secondary CIDR block cannot be selected.
