PolarDB-X 1.0 allows you to switch zones for instances. You can switch the zone of a PolarDB-X 1.0 instance if an inappropriate zone is selected for the instance or the quota in the original zone is insufficient.

Note

  • Typically, it takes about one to two minutes to switch zones. We recommend that you switch zones during off-peak hours to avoid business interruptions.
  • A transient disconnection within seconds may occur when you switch zones. Make sure that your application client supports automatic reconnection.

  1. Log on to the PolarDB-X 1.0 console.
  2. In the top navigation bar, select the region where the target instance is located.
  3. In the left-side navigation pane, click Instances.
  4. Find the target instance and click the instance ID to go to the Basic Information page.
