Migrating a Node

Function

This API is used to migrate a node from a specified cluster to another cluster. The node can be migrated only between different clusters in the same VPC and project, and the cluster types before and after the migration must be the same.

BMS nodes in a CCE Turbo cluster cannot be migrated.

The URL for cluster management is in the format of https://Endpoint/uri, where uri indicates the resource path for API access.

Constraints

  • Nodes can be migrated only between clusters in the same VPC and project.

  • Nodes cannot be migrated between CCE Turbo clusters and CCE standard clusters.

  • Nodes cannot be migrated between DeC and non-DeC clusters.

  • Nodes cannot be migrated between clusters with IPv6 enabled and clusters without IPv6 enabled.

  • Nodes can be migrated only to the default node pool of the target cluster.

  • Nodes that have only one system disk attached cannot be migrated.

  • Physical ECS nodes in a CCE Turbo cluster cannot be migrated.
