MigrateEcu - Enterprise Distributed Application Service - Alibaba Cloud Documentation Center

Migrates an elastic compute unit (ECU) to the default cluster in a specified namespace.

Operation description

Limits

We recommend that you do not call this operation. Instead, we recommend that you call the TransformClusterMember operation. For more information, see TransformClusterMember .

When you call this operation to import an Elastic Compute Service (ECS) instance, the operating system of the ECS instance is reinstalled. After the operating system is reinstalled, all data of the ECS instance is deleted. You must set a logon password for the ECS instance. Make sure that no important data exists on or data has been backed up for the ECS instance that you want to import.

Terms

Namespace: the logical concept that is used to isolate resources and microservices in Enterprise Distributed Application Service (EDAS). The resources include clusters, ECS instances, and applications. You can use a default or custom namespace. Each region has a default namespace and supports multiple custom namespaces. By default, only the default namespace is available. You do not need to create a custom namespace if you do not want to isolate resources or microservices.
ECU: After an ECS instance is imported to a cluster, the instance becomes an ECU.
Elastic compute container (ECC): After you deploy an application to an ECU in a cluster, the ECU becomes an ECC.

Debugging
