Cluster migration method, related apparatus, and storage medium

Abstract

Embodiments of the present application relate to the field of cloud services, and provide a cluster migration method, related devices and a storage medium. The cluster migration method is applied to a migration control node in a cluster migration system. The cluster migration system further includes a source cluster and a target container environment which are separately deployed. The target container environment includes a plurality of first nodes, the source cluster includes a plurality of second nodes, the number of the first nodes is the same as the number of the second nodes. The method includes: adding each first node to the source cluster to obtain a transition cluster; the transition cluster includes all the first nodes and all the second nodes; in the transition cluster, migrating data of all partitions in each second node to each first node respectively; wherein, the first nodes and the second nodes correspond to each other, each second node stores a plurality of partition data; updating configuration information of all nodes in the transition cluster to obtain a target cluster, the target cluster only includes the first nodes.
