How Do I Migrate a CSS Cluster Across Regions?

CSS clusters cannot be directly migrated. You can back up a cluster to an OBS bucket and restore it to a new region.

• If the OBS bucket is in the same region as your CSS cluster, migrate the cluster by following the instructions in the section "Index Backup and Restoration".
• If the OBS bucket is not in the same region as your CSS cluster, back up the cluster to the bucket by referring to the section "Configuring Cross-Region Replication" and migrate the cluster by referring to the section "Index Backup and Restoration" of Object Storage Service User Guide.

• Before cross-region replication, ensure the snapshot folder of the destination cluster is empty. Otherwise, the snapshot information cannot be updated to the snapshot list of the destination cluster.
• Before every migration, ensure the folder is empty.
