| Migrating data between Huawei Cloud Elasticsearch clusters | Huawei Cloud Logstash | - Migrate data from a Huawei Cloud Elasticsearch cluster of an earlier version to one of a later version.
- Migrate data from multiple Huawei Cloud Elasticsearch clusters to a single such cluster to form a unified data platform.
| During cluster migration, do not add, delete, or modify indexes in the source cluster, or the source and destination clusters will have inconsistent data after the migration. | Migrating Data Between Elasticsearch Clusters Using Huawei Cloud Logstash |
| Backup and restoration | - Migrate data between Huawei Cloud Elasticsearch clusters in the same region or across regions, and under the same or different accounts.
- Migrate data from a Huawei Cloud Elasticsearch cluster of an earlier version to one of a later version.
- Migrate data from multiple Huawei Cloud Elasticsearch clusters to a single such cluster to form a unified data platform.
| The version of the destination cluster must not be earlier than that of the source cluster. For details, see Snapshot version compatibility. | Migrating Data Between Huawei Cloud Elasticsearch Clusters Using Backup and Restoration |
| Read/write splitting plugin | - Migrate data between Huawei Cloud Elasticsearch clusters in the same region or across regions, and under the same or different accounts.
- Migrate data from multiple Huawei Cloud Elasticsearch clusters to a single such cluster to form a unified data platform.
