Target customers: users who need to migrate instances across VPCs. Features released: ECS now supports the feature of changing VPCs for subscription instances to help you re-plan your network architecture in the following scenarios: 1. Poorly planned VPCs cannot meet increasing business requirements. 2. Different projects and environments share a single VPC, which causes risks in data operations. You need to plan VPCs by project or environment and migrate projects by changing VPCs of ECS instances. 3. Cross-account VPC interconnection is required. ECS instances are located in the default VPCs of different accounts, and the VPCs cannot be interconnected due to IP address conflicts. You need to solve the address conflicts by changing the VPCs of the ECS instances to allow cross-account VPC interconnection.
