Migration Process

The container migration service of UCS allows you to migrate applications from the Kubernetes cluster on a third-party cloud to a Huawei Cloud cluster or multi-cloud cluster of UCS for cross-cloud migration and unified management.

Figure 1 Migration process

The process is as follows:

1. Cluster evaluation

   In this phase, you will evaluate the status of the source cluster to determine the type of the destination cluster. UCS kspider can automatically collect information about the source cluster, including the Kubernetes version, cluster scale, workload, and storage, and provide you with information about the recommended destination cluster. For details, see Cluster Evaluation.

2. Data migration

   In this phase, you will migrate images and data related to dependent services to the cloud. UCS image-migrator is an automatic image migration tool. It can migrate images from the image repository on a third-party cloud to SWR. To migrate data of dependent services, you can use other Huawei Cloud products together with image-migrator.

3. Application backup

   In this phase, you will back up applications in the cluster on a third-party cloud. UCS k8clone can automatically collect Kubernetes metadata and save it as a compressed package to the local host to back up applications in the cluster. For details, see Application Backup.

4. Application migration

   In this phase, you will restore backup data to migrate applications from the cluster on a third-party cloud to a Huawei Cloud cluster or multi-cloud cluster of UCS. For details, see Application Migration.
