Supported Databases

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 include on-premises databases and databases created on ECSs. RDS for MySQL refers to the MySQL databases created using RDS.

The destination database version must be the same as or later than the source database version.

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 3 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 consistent. In this way, data of critical workloads can move between different systems 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 include on-premises databases and databases created on ECSs. RDS for MySQL refers to the MySQL databases created using RDS.

The destination database version must be the same as or later than the source database version.
