When the access address of a database instance needs to be modified, you can adjust the network using the private network translation feature.
- Modifying the private address of an instance is highly risky. Please only do so with caution during off-peak hours. After modification, unless occupied by another service, the original address will remain valid for another 24 hours. Please switch your business configuration as soon as possible.
- Once selected, a VPC cannot be changed.
An instance can be switched from classic network to VPC. To do so, log in to the TDSQL Console, click an instance name in the instance list, and click Switch to VPC in the "Network" section on the instance details page (provided that there is an available IP in the target VPC subnet).
The private address of a TencentDB instance can be changed. You can do so in the Private IP section on the instance details page, provided that there is an available IP in the current subnet.
The VPC subnet of an instance can be changed. To do so, click Change Subnet in the Network section on the instance details page, provided that there is an available IP in the target VPC subnet.
Because the product supports an intra-city active-active architecture, you are recommended to choose a VPC subnet in the same region as your business server or master node.
