You can call this operation to migrate an instance from one zone to another.

For example, if Instance 1 is located in zone cn-hangzhou-a of China (Hangzhou), you can call this operation to migrate the instance to zone cn-hangzhou-b of China (Hangzhou).

Note In cross-zone migration, instances must be migrated within the same region. For example, instances in a zone of China (Hangzhou) cannot be migrated to zones of China (Qingdao).
