Supported Databases
DRS supports data flows between different DB engines. This section lists the supported databases in real-time migration, backup migration, real-time synchronization, data subscription, and real-time DR.
Real-Time Migration
You can migrate all database objects across cloud platforms, from on-premises databases to the cloud, or across regions on the cloud in real time. The following table lists the supported databases, versions, and migration types. For more information about real-time migration, see Real-Time Migration.
Self-managed databases (such as MySQL and MongoDB) include on-premises databases and databases created on an ECS. RDS for MySQL refers to the MySQL databases on Huawei Cloud RDS instances.
- Some functions are only available for whitelisted users. To use these functions, submit a service ticket. In the upper right corner of the management console, choose Service Tickets > Create Service Ticket.
- The destination database version must be the same as or later than the source database version.

- Replica set -> Cluster
- Cluster -> Cluster
- Cluster -> Replica set
NOTE:- If the source is a DDS cluster instance, the incremental migration can only be performed in the VPC network.
- To perform a full+incremental migration for a single node instance, the source database must be a Huawei Cloud single node instance.

Backup Migration
You can export data from the source database to a backup file, upload the backup file to OBS, and then restore the backup file to the destination database. In this way, data migration can be complete without exposing your source database to the Internet. Table 8 lists the supported databases, versions, and migration types. For more information about backup migration, see Backup Migration.
The major version of the destination database must be the same as or later than that of the source database.

Real-Time Synchronization
Real-time synchronization refers to the process of copying data from one data source to another database while keeping data consistency. In this way, the data of key services can flow in real time. The following table lists the supported databases, versions, and synchronization types. For more information about real-time synchronization, see Real-Time Synchronization.
Self-managed databases (such as MySQL, Oracle, and PostgreSQL) include on-premises databases and databases created on an ECS. RDS for MySQL refers to the MySQL databases on Huawei Cloud RDS instances.
- Some functions are only available for whitelisted users. To use these functions, submit a service ticket. In the upper right corner of the management console, choose Service Tickets > Create Service Ticket.
- The destination database version must be the same as or later than the source database version.

Data Subscription
Data subscription is used to obtain data changes of key services in the database. DRS caches the data changes and provides a unified SDK interface for downstream services to subscribe to, obtain, and consume the changes. Table 25 describes the supported databases and data types. For details about data subscription, see Data Subscription.
Real-Time Disaster Recovery
To prevent service unavailability caused by regional faults, DRS provides disaster recovery to ensure service continuity. The floowing table lists the databases and versions supported by real-time DR. For more information about real-time DR, see Real-Time Disaster Recovery.
Self-managed databases (for example, MySQL) refer to on-premises databases and the databases created on an ECS. RDS for MySQL refers to the MySQL databases on Huawei Cloud RDS instances.
- Some functions are only available for whitelisted users. To use these functions, submit a service ticket. In the upper right corner of the management console, choose Service Tickets > Create Service Ticket.

Workload Replay
A workload replay task simulates the service load of the source database on the destination database so you can evaluate the effectiveness and performance of the destination database. Table 28 lists the supported databases and versions. For more information about workload replay, see Workload Replay.
Self-managed databases (such as MySQL and MariaDB) refer to on-premises databases and databases created on an ECS. RDS for MySQL refers to the MySQL databases on Huawei Cloud RDS instances.
