This topic describes how to use OceanBase Migration Service (OMS) to migrate data from a MySQL tenant of OceanBase Database to a MySQL database.
Background information
You can create a data migration project in the OMS console to seamlessly migrate the existing business data and incremental data from a MySQL tenant of OceanBase Database to a MySQL database through schema migration, full migration, and incremental synchronization.
MySQL Database supports the following modes: primary database only, standby database only, and primary/standby databases. The following table describes the data migration operations supported by each mode.
| Mode | Supported operations |
|---|---|
| Primary database only | Schema migration, full migration, incremental synchronization, full verification, and reverse incremental migration |
| Standby database only | A MySQL database in this mode cannot serve as the destination for data migration. |
| Primary/standby databases | Primary database: schema migration, full migration, incremental synchronization, and reverse incremental migration Secondary database: full verification NoteIf this mode is selected, OMS uses the standby database as the primary node for full verification. |
