OceanBase Migration Assessment (OMA) provides accurate compatibility assessment for data migration. This topic describes the types and versions of databases that support compatibility assessment.
Background information
OMA assesses the compatibility of converting database objects of Oracle Database, MySQL, PostgreSQL, TiDB, DB2 LUW, RDS for MySQL, PolarDB for MySQL, PolarDB for Oracle, DRDS, SQL Server, openGauss, and OceanBase Database instances (both MySQL and Oracle tenants) to database objects of OceanBase Database, and provides profile analysis and automatic conversion solutions.
