Can CSS Clusters Be Migrated Across Different Regions?¶
In CSS, perform the following to migrate Elasticsearch clusters across different regions:
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.
Note
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.
