# 第 3 阶段：迁移
<a name="migrate"></a>

在此阶段，您需要迁移数据。Oracle 支持多种迁移工具。您可以根据数据库可用性要求（在线或离线迁移）、许可、迁移策略和数据库目标等因素选择适当的数据迁移工具。

Oracle 提供原生工具，例如 [Oracle 数据泵导出和导入](https://docs.oracle.com/cd/E11882_01/server.112/e22490/part_dp.htm)、[Oracle Recovery Manager (RMAN)](https://docs.oracle.com/cd/E29505_01/backup.1111/e10642/rcmquick.htm) GoldenGate、[甲骨文和 Oracle](https://www.oracle.com/au/integration/goldengate/#:~:text=OCI%20GoldenGate%20is%20a%20real,in%20the%20Oracle%20Cloud%20Infrastructure.) [Data Guard](https://docs.oracle.com/en/database/oracle/oracle-database/19/sbydb/introduction-to-oracle-data-guard-concepts.html)。诸如之类的其他工具是补充性的 [AWS DMS](https://docs.aws.amazon.com/dms/latest/userguide/Welcome.html)，可以帮助移民。例如，您可以将 [Oracle Data Pump 导出和导入与一起](https://aws.amazon.com/blogs/database/migrating-oracle-databases-with-near-zero-downtime-using-aws-dms/)使用 AWS DMS，在停机时间接近零的情况下执行在线迁移。

下表列出了迁移工具及其支持的目标。
