Change Availability Zone

Updated at：2025-10-20

Operation scenarios

When planning to upgrade the model and the required model isn't available in the current AZ, you can migrate the instance to another AZ using the cross-AZ migration feature before initiating the model upgrade.

Prerequisites

  • Local disk instances do not support changing availability zones.
  • If the instance has an elastic network interface, please release it first
  • If the primary network interface card of the instance has secondary IP address, please release them first
  • If the instance has an IPv6 IP, please release it first
  • Changing the availability zone will restart the cloud server, causing it to stop for a few minutes. Please prepare a contingency plan before confirming this operation to ensure that your services are not affected

Operation steps

  1. Sign in to BCC Console and enter the Instance List page.
  2. You can select different operation types as needed to change the availability zone of an instance:
  • In the right-hand operation bar, click on More - Deployment & Migration - Change Availability Zone.

  • Click on the instance name to enter the Instance Information page and click the Modify button after the region.

  1. On the operation page, select the corresponding configuration and click OK for submission. The instance will enter the migration status.

  1. After the migration is completed, the instance will return to the running or stopped status.
