Operation Scenario

Tencent Cloud supports basic network and VPC, which are capable of offering a diversity of smooth services. On this basis, we provide more flexible services as shown below to help you manage network connectivity with ease.

  • Network switch
    • Switch from basic network to VPC: A single TencentDB instance can be switched from basic network to VPC.
    • Switch from VPC A to VPC B: A single TencentDB instance can be switched from VPC A to VPC B.
  • Custom IP


  • Switching the network may cause the change of instance IP. The original IP will become invalid after 24 hours. Please modify the instance IP on the client in a timely manner.
  • To prevent abuse of IP resources, you can switch network once every 24 hours.
  • Only VPCs and subnets in the region and AZ where the instance reside can be selected.
  • The switch from basic network to VPC is irreversible. After the switch to a VPC, the TencentDB instance cannot communicate with Tencent Cloud services in another VPC or basic network.
  • Instances where the data replication mode is strong sync replication do not support the above-mentioned switches.
