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 Index Backup and Restoration.
If the OBS bucket is not in the same region as your CSS cluster, configure cross-region replication to back up the cluster to the bucket, and migrate the cluster by following the instructions in Index Backup and Restoration.

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.
