# 階段 3：遷移
<a name="migrate"></a>

在此階段，您會遷移資料。Oracle 支援各種遷移工具。您可以根據資料庫可用性需求 （線上或離線遷移）、授權、遷移策略和資料庫目標等因素，選擇適當的資料遷移工具。

Oracle 提供原生工具，例如 [Oracle Data Pump Export and Import](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)、[Oracle GoldenGate](https://www.oracle.com/au/integration/goldengate/#:~:text=OCI%20GoldenGate%20is%20a%20real,in%20the%20Oracle%20Cloud%20Infrastructure.) 和 [Oracle Data Guard](https://docs.oracle.com/en/database/oracle/oracle-database/19/sbydb/introduction-to-oracle-data-guard-concepts.html)。其他工具，例如 [AWS DMS](https://docs.aws.amazon.com/dms/latest/userguide/Welcome.html)是互補的，有助於遷移。例如，您可以使用 [Oracle Data Pump 匯出和匯入搭配 AWS DMS](https://aws.amazon.com/blogs/database/migrating-oracle-databases-with-near-zero-downtime-using-aws-dms/) ，在幾乎零停機時間的情況下執行線上遷移。

下表列出遷移工具和其支援的目標。
