Modifying a VPC

Scenarios

Change the VPC name and CIDR block.

If the VPC CIDR block conflicts with the CIDR block of a VPN created in the VPC, you can modify its CIDR block.

Notes and Constraints

  • When modifying the VPC CIDR block:
    • The VPC CIDR block to be modified must be in the supported CIDR blocks: 10.0.0.0 - 10.255.255.255, 172.16.0.0 - 172.31.255.255, and 192.168.0.0 - 192.168.255.255
    • If the VPC has subnets, the VPC CIDR block to be modified must contain all subnet CIDR blocks.
