Migrates an ECS instance to a dedicated host (DDH) in the same region.

Description

You can call the ModifyInstanceDeployment operation to complete the following tasks:

  • Add an instance to a deployment set, or migrate an instance from one deployment set to another. The DeploymentSetId parameter is required for this task.
  • You can migrate ECS instances from a shared host to the specified DDH, or migrate instances between two DDHs to reallocate you resources. The DedicatedHostId parameter is required for this task.

When migrating an ECS instance to a DDH, note that:

  • Make sure that the instance is in the Stopped state. The instance automatically restarts after migration.
  • You can only migrate VPC-connected ECS instances.

Debugging

You can use API Explorer to perform debugging. API Explorer allows you to perform various operations to simplify API usage. For example, you can retrieve APIs, call APIs, and dynamically generate SDK example code.
