您可以使用 Database Migration Service 将数据库迁移到 Google Cloud。
Database Migration Service 同时支持同构迁移（例如从 MySQL 迁移到 Cloud SQL for MySQL）和异构迁移（例如从 Oracle 迁移到 Cloud SQL for PostgreSQL）。
本页面列出了 Database Migration Service 在所有迁移方案中支持的所有源数据库和目标数据库的版本。您可以使用此信息来选择迁移的源数据库和目标数据库。
同构迁移支持的源数据库和目标数据库
选择同构迁移方案，查看迁移支持哪些来源数据库和目标数据库：
